Letter O in Different Fonts

Every styled version of O below is ordinary Unicode, not a font file. That is why it pastes into an Instagram bio, a Discord name or a TikTok caption with nothing installed — and also why some styles are missing letters entirely.

Which styles have no O

31 of our 33 styles can render O. The 2 that cannot are Upside Down and Mirror Text. Those alphabets were never completed in Unicode, so a generator that claims to offer them will hand back a plain o sitting in the middle of otherwise styled text — the single most common way a styled name ends up looking broken.

If you are styling a word that starts with O, check it in the generator above before you paste it. A style that looks right for one letter can break on the next.

Every O in Unicode, with codepoints

The letter O is drawn from 9 different Unicode blocks, mostly Mathematical Alphanumeric Symbols. Codepoints are listed so you can use them directly in code.

Where O breaks

Styled letters are real characters, so whether they survive depends on the platform, not on us. Instagram accepts almost all of them in a bio but strips some from a display name. Discord renders them in messages and nicknames, though a server with a name-format rule may reject them. Most search boxes will not match them, so a username in 𝐨 form is not findable by typing o.

Screen readers are the case worth taking seriously: a mathematical-alphanumeric O may be read out as "mathematical bold small o" or skipped. Fine for a decorative caption, poor for anything that has to be read.
