Unicode font converter

How a font converter works

A font converter does not change any font. It swaps each letter for a different character that already looks styled. The plain letter A is character U+0041. Its bold twin, 𝐀, is a separate character: U+1D400, MATHEMATICAL BOLD CAPITAL A.

The app that shows your text still uses its own normal font. It just draws a different character.

Where these letters live in Unicode

Unicode sorts characters into blocks. Most real styles come from one block: Mathematical Alphanumeric Symbols, U+1D400 to U+1D7FF. It was added in Unicode 3.1 in 2001 so that math papers could use bold, script and gothic letters as different symbols.

A few letters were already in Unicode before that block existed, in a block called Letterlike Symbols. The math block leaves holes for them. That is why double struck ℂ, ℍ, ℕ, ℙ, ℚ, ℝ and ℤ have much lower numbers than the other double struck letters.

Real styles and lookalikes

The math styles are complete letter sets made on purpose. Lookalikes are different. They borrow letters from Greek, Cyrillic, Thai, Ethiopic, Cherokee and other alphabets that happen to look like Latin letters. To someone who reads those alphabets, a lookalike name is a string of random letters.

Both kinds work in most apps. Lookalikes cause more trouble with search, translation and screen readers, so use them for decoration, not for names people need to find.

Why some styles show as boxes

Your phone draws every character with a font. If none of its fonts has a picture for a character, you see an empty box, sometimes called tofu, or a question mark. The math letters are covered on almost every phone and computer today. Rare lookalike letters, like the Yi syllables in the Shaky style, are missing on more devices.

What counts is the reader's phone, not yours. When in doubt, pick a math style and test it on a friend's phone.

How screen readers read fancy fonts

Screen readers read text out loud for people who can't see the screen. Some of them read 𝐇𝐢 as "mathematical bold capital H, mathematical bold small i". Others skip the letters, and lookalikes may be read as words in another language. Keep your name and important words plain, and style only a word or two. You can hear an example on the fancy text page.

Character limits and the "counts as 2" trap

Most math letters sit far out in Unicode, past number 65,535. Computers store each of them as two pieces of 16 bits. Many apps count those pieces, not the letters you see, so a 10 letter bold name may count as 20 characters.

Styles like small caps, circled letters and wide letters stay at one piece per letter. They are the safest choice when a name field has a tight limit. For circled and squared letters in five styles, use the bubble text generator.
