- Where does unicode italic work?
- Social media (Twitter/X, Instagram, LinkedIn), chat apps (Slack, Discord), and any UTF-8 text field. Common failure points: email subject lines and URL slugs.
- Is unicode italic searchable?
- Barely. Search engines treat italic codepoints as distinct from ASCII. A person searching for 'italic' won't match 'italic' in a unicode-italicized post. Use sparingly.
- What's the difference from CSS italic?
- CSS italic changes the font rendering of standard ASCII letters. Unicode italic is a separate character set. Only CSS italic is accessible and searchable.
- Does it work in code blocks?
- It works in prose text. Inside code blocks on most platforms, the unicode italic characters display as-is โ which is almost never what you want for code.
