Characters without an exact Unicode counterpart are preserved. Appearance and accessibility can vary by font, operating system and destination app.

Bold that travels with the text

Unicode contains bold serif and sans-serif mathematical alphabets. SymbolDex swaps letters for those code points instead of adding HTML tags or Markdown.

Compatibility limits

Rendering depends on font support, and styled characters can behave differently in search, sorting and assistive technology.
