Key facts
- Fancy letters are separate Unicode characters, not fonts: bold, script, double-struck and circled forms of A are four different characters.
- Unicode added the mathematical alphabets in 2001 and reused older Letterlike Symbols characters where letters already existed, leaving gaps.
- The script alphabet borrows 11 letters from the older Letterlike Symbols block, and the double-struck alphabet borrows 7.
- Bold script, bold Fraktur, bold and sans-serif alphabets have no gaps, so they look the most consistent.
- A code point is the number Unicode assigns to a character, written like U+1D4D0.
- Unicode has no small-caps X, and subscript letters exist for only 17 letters.
Why does one letter have dozens of versions?
To a computer, the bold 𝐀, the script 𝒜, the double-struck 𝔸 and the circled Ⓐ are completely different characters, not one A in different fonts. Unicode encodes them separately because mathematicians, phoneticians and East Asian typesetters each needed distinct symbols:
- Mathematics needed letter variants that mean different things: 𝐯 for a vector, ℝ for the real numbers, 𝔤 for a Lie algebra. That produced bold, italic, script, Fraktur, double-struck, sans-serif and monospace alphabets.
- Phonetics needed small capitals (ʙ, ʀ, ɢ) and superscript letters (ʰ, ʷ) to write sounds precisely.
- CJK typesetting needed full-width Latin letters (A) that line up with Chinese and Japanese characters.
- Enclosed letters (Ⓐ, 🅐, 🄰) came from legacy character sets used for lists and labels.
Because they’re real characters, they copy and paste anywhere. The trade-off is that search engines, screen readers and spell-checkers treat them as symbols, not letters.
Which fancy letters have gaps in Unicode?
When Unicode added the maths alphabets in 2001, some letters already existed in the Letterlike Symbols block (U+2100–214F), so Unicode left holes and reused the older characters. They’re often drawn in a slightly different style, which is why a styled word can look uneven:
| Alphabet | Borrowed letters |
|---|---|
| Script | ℬ ℰ ℱ ℋ ℐ ℒ ℳ ℛ ℯ ℊ ℴ |
| Fraktur | ℭ ℌ ℑ ℜ ℨ |
| Double-struck | ℂ ℍ ℕ ℙ ℚ ℝ ℤ |
| Italic | ℎ (the Planck constant) |
Bold script, bold Fraktur, bold and sans-serif alphabets have no gaps, so they look the most consistent.
Each letter page lists exactly which of its forms are borrowed, along with its history and its handwritten cursive form.
Where should I go from here?
The Greek letters have their own section: the Greek alphabet page lists all 24 with names, sounds and Unicode. To convert whole words at once, use the lettering generator, and to turn styled text back into plain letters, use the Unstyle text tool. Pick a letter above whenever you need one of these fancy letters on its own.
