* Encodes a string to UTF-16.

* @param input The string to be encoded.
* @param byteOrderMark Whether or not a byte order marker (BOM) should be added
* to the start of the encoding. (default `true`)
* @returns A Uint16Array containing the UTF-16 encoding of the input string.
*
* -----------------------------------------------------------------------------
*
* JavaScript strings are composed of Unicode code points. Code points are
* integers in the range 0 to 1,114,111 (0x10FFFF). When serializing a string,
* it must be encoded as a sequence of words. A word is typically 8, 16, or 32
* bytes in size. As such, Unicode defines three encoding forms: UTF-8, UTF-16,
* and UTF-32. These encoding forms are described in the Unicode standard [1].
* This function implements the UTF-16 encoding form.
*
* -----------------------------------------------------------------------------
*
* In UTF-16, each code point is mapped to one or two 16-bit integers. The
* UTF-16 mapping logic is as follows [2]:
*
* • If a code point is in the range U+0000..U+FFFF, then map the code point to
* a 16-bit integer with the most significant byte first.
*
* • If a code point is in the range U+10000..U+10000, then map the code point
* to two 16-bit integers. The first integer should contain the high surrogate
* and the second integer should contain the low surrogate. Both surrogates
* should be written with the most significant byte first.
*
* -----------------------------------------------------------------------------
*
* It is important to note, when iterating through the code points of a string
* in JavaScript, that if a character is encoded as a surrogate pair it will
* increase the string's length by 2 instead of 1 [4]. For example:
*
* ```
* > 'a'.length
* 1
* > '💩'.length
* 2
* > '語'.length
* 1
* > 'a💩語'.length
* 4
* ```
*
* The results of the above example are explained by the fact that the
* characters 'a' and '語' are not represented by surrogate pairs, but '💩' is.
*
* Because of this idiosyncrasy in JavaScript's string implementation and APIs,
* we must "jump" an extra index after encoding a character as a surrogate
* pair. In practice, this means we must increment the index of our for loop by
* 2 if we encode a surrogate pair, and 1 in all other cases.
*

*
* Sends input data to deflate pipe, generating [[Deflate#onData]] calls with
* new compressed chunks. Returns `true` on success. The last data block must have
* mode Z_FINISH (or `true`). That will flush internal pending buffers and call

/*
Decode literal, length, and distance codes and write out the resulting
literal and match bytes until either not enough input or output is
available, an end-of-block is encountered, or a data error is encountered.
When large enough input and output buffers are supplied to inflate(), for
example, a 16K input buffer and a 64K output buffer, more than 95% of the
inflate execution time is spent in this routine.
Entry assumptions:
state.mode === LEN
strm.avail_in >= 6
strm.avail_out >= 258
start >= strm.avail_out
state.bits < 8
On return, state.mode is one of:
LEN -- ran out of enough output space or enough available input
TYPE -- reached end of block code, inflate() to interpret next block
BAD -- error in block data
Notes:
- The maximum input bits used by a length/distance pair is 15 bits for the
length code, 5 bits for the length extra, 15 bits for the distance code,
and 13 bits for the distance extra. This totals 48 bits, or six bytes.
Therefore if strm.avail_in >= 6, then there is enough input to avoid
checking for available input while decoding.
- The maximum bytes that a single length/distance pair can output is 258
bytes, which is the maximum length that can be coded. inflate_fast()
requires strm.avail_out >= 258 for each loop to avoid checking for
output space.

Process a set of code lengths to create a canonical Huffman code. The
code lengths are lens[0..codes-1]. Each length corresponds to the
symbols 0..codes-1. The Huffman code is generated by first sorting the
symbols by length from short to long, and retaining the symbol order
for codes with equal lengths. Then the code starts with all zero bits
for the first code of the shortest length, and the codes are integer
increments for the same length, and zeros are appended as the length
increases. For the deflate format, these bits are stored backwards
from their more natural integer increment ordering, and so when the
decoding tables are built in the large loop below, the integer codes
are incremented backwards.
This routine assumes, but does not check, that all of the entries in
lens[] are in the range 0..MAXBITS. The caller must assure this.
1..MAXBITS is interpreted as that code length. zero means that that
symbol does not occur in this code.
The codes are sorted by computing a count of codes for each length,
creating from that a table of starting indices for each length in the
sorted table, and then entering the symbols in order in the sorted
table. The sorted table is work[], with that space being provided by
the caller.
The length counts are used for other purposes as well, i.e. finding
the minimum and maximum length codes, determining if there are any
codes at all, checking for a valid set of lengths, and looking ahead
at length counts to determine sub-table sizes when building the
decoding tables.

Create and fill in decoding tables. In this loop, the table being
filled is at next and has curr index bits. The code being used is huff
with length len. That code is converted to an index by dropping drop
bits off of the bottom. For codes where len is less than drop + curr,
those top drop + curr - len bits are incremented through all values to
fill the table with replicated entries.
root is the number of index bits for the root table. When len exceeds
root, sub-tables are created pointed to by the root entry with an index
of the low root bits of huff. This is saved in low to check for when a
new sub-table should be started. drop is zero when the root table is
being filled, and drop is root when sub-tables are being filled.
When a new sub-table is needed, it is necessary to look ahead in the
code lengths to determine what size sub-table is needed. The length
counts are used for this, and so count[] is decremented as codes are
entered in the tables.
used keeps track of how many table entries have been allocated from the
provided *table space. It is checked for LENS and DIST tables against
the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in
the initial root table size constants. See the comments in inftrees.h
for more information.
sym increments through all symbols, and the loop terminates when
all codes of length max, i.e. all codes, have been processed. This
routine permits incomplete codes, so another loop after this one fills
in the rest of the decoding tables with invalid code markers.

when a window is already in use, or when output has been written during this
inflate call, but the end of the deflate stream has not been reached yet.
It is also called to create a window for dictionary data when a dictionary
is loaded.
Providing output buffers larger than 32K to inflate() should provide a speed
advantage, since only the last 32K of output is copied to the sliding window
upon return from inflate(), and since all distances after the first 32K of
output will fall in the output data, making match copies simpler and faster.
The advantage may be dependent on the size of the processor's data caches.

*
* [http://zlib.net/manual.html#Advanced](http://zlib.net/manual.html#Advanced)
* for more information on these.
*
* Additional options, for internal needs:
*
* - `chunkSize` - size of generated data chunks (16K by default)
* - `raw` (Boolean) - do raw inflate
* - `to` (String) - if equal to 'string', then result will be converted

* By default, when no options set, autodetect deflate/gzip data format via
* wrapper header.

*
* ```javascript
* var pako = require('pako')
* , chunk1 = Uint8Array([1,2,3,4,5,6,7,8,9])
* , chunk2 = Uint8Array([10,11,12,13,14,15,16,17,18,19]);
*
* var inflate = new pako.Inflate({ level: 3});
*
* inflate.push(chunk1, false);

* Inflate#push(data[, mode]) -> Boolean
* - data (Uint8Array|Array|ArrayBuffer|String): input data
* - mode (Number|Boolean): 0..6 for corresponding Z_NO_FLUSH..Z_TREE modes.
* See constants. Skipped or `false` means Z_NO_FLUSH, `true` means Z_FINISH.
*
* Sends input data to inflate pipe, generating [[Inflate#onData]] calls with
* new output chunks. Returns `true` on success. The last data block must have
* mode Z_FINISH (or `true`). That will flush internal pending buffers and call
* [[Inflate#onEnd]]. For interim explicit flushes (without ending the stream) you
* can use mode Z_SYNC_FLUSH, keeping the decompression context.
*
* On fail call [[Inflate#onEnd]] with error code and return false.
*
* We strongly recommend to use `Uint8Array` on input for best speed (output
* format is detected automatically). Also, don't skip last param and always
* use the same type in your code (boolean or number). That will improve JS speed.
*
* For regular `Array`-s make sure all elements are [0..255].
*
* ##### Example
*
* ```javascript
* push(chunk, false); // push one of data chunks
* ...
* push(chunk, true); // push last chunk
* ```

* - `to` (String) - if equal to 'string', then result will be converted
* from utf8 to utf16 (javascript) string. When string output requested,
* chunk length can differ from `chunkSize`, depending on content.

* PDFObjectCopier copies PDFObjects from a src context to a dest context.

*
* ```

// A check mark is defined by three points in some coordinate space. Here, we
// define these points in a unit coordinate system, where the range of the x
// and y axis are both [-1, 1].
//
// Note that we do not hard code `p1y` in case we wish to change the
// size/shape of the check mark in the future. We want the check mark to
// always form a right angle. This means that the dot product between (p1-p2)
// and (p3-p2) should be zero:
//
// (p1x-p2x) * (p3x-p2x) + (p1y-p2y) * (p3y-p2y) = 0
//
// We can now rejigger this equation to solve for `p1y`:
//
// (p1y-p2y) * (p3y-p2y) = -((p1x-p2x) * (p3x-p2x))
// (p1y-p2y) = -((p1x-p2x) * (p3x-p2x)) / (p3y-p2y)
// p1y = -((p1x-p2x) * (p3x-p2x)) / (p3y-p2y) + p2y
//

* @description
* Return the date parsed from string using the given format string.
*
* > ⚠️ Please note that the `format` tokens differ from Moment.js and other libraries.
* > See: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md
*
* The characters in the format string wrapped between two single quotes characters (') are escaped.
* Two single quotes in a row, whether inside or outside a quoted sequence, represent a 'real' single quote.
*
* Format of the format string is based on Unicode Technical Standard #35:
* https://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table
* with a few additions (see note 5 below the table).
*
* Not all tokens are compatible. Combinations that don't make sense or could lead to bugs are prohibited
* and will throw `RangeError`. For example usage of 24-hour format token with AM/PM token will throw an exception:
*
* ```javascript
* parse('23 AM', 'HH a', new Date())
* //=> RangeError: The format string mustn't contain `HH` and `a` at the same time
* ```
*
* See the compatibility table: https://docs.google.com/spreadsheets/d/e/2PACX-1vQOPU3xUhplll6dyoMmVUXHKl_8CRDs6_ueLmex3SoqwhuolkuN3O05l4rqx5h1dKX8eb46Ul-CCSrq/pubhtml?gid=0&single=true

* Notes:
* 1. "Formatting" units (e.g. formatting quarter) in the default en-US locale
* are the same as "stand-alone" units, but are different in some languages.
* "Formatting" units are declined according to the rules of the language
* in the context of a date. "Stand-alone" units are always nominative singular.
* In `format` function, they will produce different result:
*
* `format(new Date(2017, 10, 6), 'do LLLL', {locale: cs}) //=> '6. listopad'`
*
* `format(new Date(2017, 10, 6), 'do MMMM', {locale: cs}) //=> '6. listopadu'`
*
* `parse` will try to match both formatting and stand-alone units interchangeably.
*
* 2. Any sequence of the identical letters is a pattern, unless it is escaped by
* the single quote characters (see below).
* If the sequence is longer than listed in table:
* - for numerical units (`yyyyyyyy`) `parse` will try to match a number
* as wide as the sequence
* - for text units (`MMMMMMMM`) `parse` will try to match the widest variation of the unit.
* These variations are marked with "2" in the last column of the table.
*
* 3. `QQQQQ` and `qqqqq` could be not strictly numerical in some locales.
* These tokens represent the shortest form of the quarter.
*
* 4. The main difference between `y` and `u` patterns are B.C. years:
*
* | Year | `y` | `u` |
* |------|-----|-----|
* | AC 1 | 1 | 1 |
* | BC 1 | 1 | 0 |
* | BC 2 | 2 | -1 |
*
* Also `yy` will try to guess the century of two digit year by proximity with `referenceDate`:
*
* `parse('50', 'yy', new Date(2018, 0, 1)) //=> Sat Jan 01 2050 00:00:00`
*
* `parse('75', 'yy', new Date(2018, 0, 1)) //=> Wed Jan 01 1975 00:00:00`
*
* while `uu` will just assign the year as is:
*
* `parse('50', 'uu', new Date(2018, 0, 1)) //=> Sat Jan 01 0050 00:00:00`
*
* `parse('75', 'uu', new Date(2018, 0, 1)) //=> Tue Jan 01 0075 00:00:00`
*
* The same difference is true for local and ISO week-numbering years (`Y` and `R`),
* except local week-numbering years are dependent on `options.weekStartsOn`
* and `options.firstWeekContainsDate` (compare [setISOWeekYear](https://date-fns.org/docs/setISOWeekYear)
* and [setWeekYear](https://date-fns.org/docs/setWeekYear)).
*
* 5. These patterns are not in the Unicode Technical Standard #35:
* - `i`: ISO day of week
* - `I`: ISO week of year
* - `R`: ISO week-numbering year
* - `o`: ordinal number modifier
* - `P`: long localized date
* - `p`: long localized time
*
* 6. `YY` and `YYYY` tokens represent week-numbering years but they are often confused with years.
* You should enable `options.useAdditionalWeekYearTokens` to use them. See: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md
*
* 7. `D` and `DD` tokens represent days of the year but they are often confused with days of the month.
* You should enable `options.useAdditionalDayOfYearTokens` to use them. See: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md
*
* 8. `P+` tokens do not have a defined priority since they are merely aliases to other tokens based
* on the given locale.
*
* using `en-US` locale: `P` => `MM/dd/yyyy`
* using `en-US` locale: `p` => `hh:mm a`
* using `pt-BR` locale: `P` => `dd/MM/yyyy`
* using `pt-BR` locale: `p` => `HH:mm`
*
* Values will be assigned to the date in the descending order of its unit's priority.
* Units of an equal priority overwrite each other in the order of appearance.
*
* If no values of higher priority are parsed (e.g. when parsing string 'January 1st' without a year),
* the values will be taken from 3rd argument `referenceDate` which works as a context of parsing.
*
* `referenceDate` must be passed for correct work of the function.
* If you're not sure which `referenceDate` to supply, create a new instance of Date:
* `parse('02/11/2014', 'MM/dd/yyyy', new Date())`
* In this case parsing will be done in the context of the current date.
* If `referenceDate` is `Invalid Date` or a value not convertible to valid `Date`,
* then `Invalid Date` will be returned.
*
* The result may vary by locale.
*
* If `formatString` matches with `dateString` but does not provides tokens, `referenceDate` will be returned.
*
* If parsing failed, `Invalid Date` will be returned.
* Invalid Date is a Date, whose time value is NaN.
* Time value of Date: http://es5.github.io/#x15.9.1.1
*
* @typeParam DateType - The `Date` type, the function operates on. Gets inferred from passed arguments. Allows to use extensions like [`UTCDate`](https://github.com/date-fns/utc).
* @typeParam ResultDate - The result `Date` type, it is the type returned from the context function if it is passed, or inferred from the arguments.
*
* @param dateStr - The string to parse
* @param formatStr - The string of tokens
* @param referenceDate - defines values missing from the parsed dateString
* @param options - An object with options.
* see: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md
* see: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md
*
* @returns The parsed date
*
* @throws `options.locale` must contain `match` property
* @throws use `yyyy` instead of `YYYY` for formatting years using [format provided] to the input [input provided]; see: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md
* @throws use `yy` instead of `YY` for formatting years using [format provided] to the input [input provided]; see: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md
* @throws use `d` instead of `D` for formatting days of the month using [format provided] to the input [input provided]; see: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md
* @throws use `dd` instead of `DD` for formatting days of the month using [format provided] to the input [input provided]; see: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md
* @throws format string contains an unescaped latin alphabet character
*
* @example
* // Parse 11 February 2014 from middle-endian format:
* var result = parse('02/11/2014', 'MM/dd/yyyy', new Date())
* //=> Tue Feb 11 2014 00:00:00
*
* @example
* // Parse 28th of February in Esperanto locale in the context of 2010 year:
* import eo from 'date-fns/locale/eo'
* var result = parse('28-a de februaro', "do 'de' MMMM", new Date(2010, 0, 1), {
* locale: eo
* })
