Bold/italic in normal <input>/<textarea> elements
This script allows you to use italic (actually 𝘪𝘵𝘢𝘭𝘪𝘤) and bold (𝗯𝗼𝗹𝗱)
inside normal <input> and <textarea> elements.

The script uses characters in the Unicode block Mathematical Alphanumeric
Symbols (U+1D400–U+1D7FF), which is not supported by most fonts. 𝘚𝘰 𝘵𝘩𝘦 𝘵𝘦𝘹𝘵

Just select the text inside a <input> or <textarea> and click Ctrl+I for italic or Ctrl+B for bold.
Only alphabetic characters are supported. Anything outside the Latin alphabet (any non-Latin script, punctuation, symbols, numbers &c) won’t be changed at all.
Accented characters will be replaced with the appropriate italic and/or bold character plus the combining character for the diacritic.
For example:
é U+00E9 LATIN SMALL LETTER E WITH ACUTE
will be italicized as
𝘦 U+1D626 MATHEMATICAL SANS-SERIF ITALIC SMALL E
◌́ U+0301 COMBINING ACUTE ACCENT
<div> elements with contenteditable="true", instead of
<input>/<textarea> elements. This script won’t work with those either. Also this script
won’t play nicely with controlled components in React or other similar frameworks.Written by André Kugland.
