How it works
These aren't new fonts — they're separate Unicode characters that happen to look styled, which is why they paste as-is into Instagram bios, Discord, TikTok captions, or anywhere else that doesn't let you change fonts normally.
What to know
A few styles (fullwidth, small caps, circled, squared, bubble, subscript, upside down) only exist for letters and numbers, so punctuation is left unchanged. Subscript only has real Unicode versions for some letters (a e h i j k l m n o p r s t u v x) — the rest stay normal-sized. Mirror only has true mirror-image versions of a few letters (b d p q c e s) — the rest stay unchanged. "Fire" and "Heart" aren't real fonts — they're bold text decorated with 🔥 or ❤️, since flame- or heart-shaped letters can't be typed on a normal keyboard. Several styles further down (Terminal, Hologram, Cyber Brackets, and similar) are decorative symbol framings built on top of the styles above them, not separate character sets of their own.
