Which Unicode styles work best in bios

Mathematical styles (bold, italic, bold italic, double-struck) have high compatibility on modern platforms because their code points have existed in the Unicode standard for over 20 years and are already included in default iOS and Android system fonts.
Styles using combining characters — strikethrough, underline, overline — depend on how the app renders Unicode diacritics. They work well in browsers but may appear misaligned in apps with custom typography.
For Instagram bios, the best choices are usually: mathematical bold (𝐀𝐁𝐂), italic (𝐴𝐵𝐶), script/cursive (𝒜𝐵𝒞) and double-struck (𝔸𝔹ℂ). Circled letters (ⓐⓑⓒ) and small caps work well as visual separators.

Frequently asked questions

Do special letters work on TikTok?

Yes. TikTok accepts Unicode in bios and comments. Mathematical styles (bold, italic, script) have good compatibility. Avoid styles with many combining characters in comments — they may appear broken on older Android.

Do these letters appear in Google search results?

Unicode characters in social media bios are not directly indexed by Google. Google indexes web pages; Instagram and TikTok bios rarely appear in search results. The focus is visual, not SEO.

Do special letters affect accessibility in a bio?

Yes. Screen readers like VoiceOver read each code point by its technical name: "MATHEMATICAL BOLD SMALL F" instead of "f". An all-bold mathematical bio may be incomprehensible to screen reader users. Use sparingly.
