The Unicode characters for superscript (modifier) IPA vowel letters, plus a pair of extended letters ᵻ ᵿ found in English dictionaries, are as follows. Recently retired alternative letters such as ɩ ɷ are also supported; they are set off in parentheses and placed below the standard IPA letters:
Superscripts and Subscripts is a Unicode block containing superscript and subscript numerals, mathematical operators, and letters used in mathematics and phonetics. The use of subscripts and superscripts in Unicode allows any polynomial, chemical and certain other equations to be represented in plain text without using any form of markup like HTML or TeX.
HTML and XML provide ways to reference Unicode characters when the characters themselves either cannot or should not be used. A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name.
For example, subscript letters on the baseline are quite rare, and many typefaces provide only a limited number of superscripted letters. Despite these differences, all reduced-size glyphs go by the same generic terms subscript and superscript , which are synonymous with the terms inferior letter (or number ) and superior letter (or number ...
The definition of a Latin-script letter for this list is a character encoded in the Unicode Standard that has a script property of 'Latin' and the general category of 'Letter'. An overview of the distribution of Latin-script letters in Unicode is given in Latin script in Unicode.
In these cases subscripts and superscripts are not merely rich text, but constitute a distinct character in the writing system (130 total). 112 characters representing abstract phonemes from phonetic alphabets such as the International Phonetic Alphabet use such positional glyphs to represent semantic differences (U+1D2C – U+1D6A, U+1D78, U+ ...
Subscripts and superscripts should be wrapped in <sub> and <sup> HTML tags, respectively, with no other formatting info, with some exceptions (see below). The {} and {} templates are useful shortcuts to the HTML markup. Do not use the Unicode subscripts and superscripts ² and ³, or XML/HTML character entity references (² etc.).
The codespace is a systematic, architecture-independent representation of The Unicode Standard; actual text is processed as binary data via one of several Unicode encodings, such as UTF-8. In this normative notation, the two-character prefix U+ always precedes a written code point, [ 62 ] and the code points themselves are written as ...
