Unicode
Although small caps are not usually "semantically important", the Unicode standard does define a number of "small capital" characters in the IPA extensions, Phonetic Extensions and Latin Extended-D ranges (0250–02AF, 1D00–1D7F, A720–A7FF). These characters, with official names such as latin letter small capital a, are meant for use in phonetic representations. For example, U+1D18 ᴘ latin letter small capital p (HTML: ᴘ) represents a semi-voiced bilabial plosive .
As of Unicode 5.1, the only characters missing to allow representation of the full Latin alphabet in small capital Unicode characters are small capital versions of Q and X. The following table collects the existing Unicode small capital characters:
| a | b | c | d | e | f | g | h | i | j | k | l | m | n | o | p | q | r | s | t | u | v | w | x | y | z |
| ᴀ | ʙ | ᴄ | ᴅ | ᴇ | ꜰ | ɢ | ʜ | ɪ | ᴊ | ᴋ | ʟ | ᴍ | ɴ | ᴏ | ᴘ | - | ʀ | ꜱ | ᴛ | ᴜ | ᴠ | ᴡ | - | ʏ | ᴢ |
Additionally, the Phonetic Extensions range has superscript "small capital" characters.
These "small capital" characters should not be confused with the Unicode Standard's typographical convention of using small caps for formal Unicode character names in running text. For example, the name of U+0416 Ж is conventionally shown as CYRILLIC CAPITAL LETTER ZHE.
