Not clear what this does? Also, copy button doesn’t work on iOS.

It lets you 𝗯𝗼𝗹𝗱 or 𝕤𝕥𝕪𝕝𝕖 stuff in unicode, so plain-text places (like Hacker News) can get formatting.

HN supports italics it's not entirely plain-text

Or perhaps HN should fix some properties formatting after all these years? Code gets posted here pretty regularly after all...

it's a wysiwyg-style editor for bold / italics / etc where it replaces the selected range with the unicode bold/etc characters.

type some text, then select it. that'll give you a format editor.

A little faded gray hint could have helped :)
