Superscript letters in Unicode

As part of my work on the National Gallery‘s Collections Information Project, I’ve commissioned the conversion of the Gallery’s paintings catalogues into TEI-compliant XML, so that we can reuse these valuable texts in different contexts. One of the questions our suppliers asked was how to encode a quotation that featured a series of abbreviations that were rendered as superscript characters. Looking into this, I realised that there doesn’t seem to be an easily-available resource on the web that lists both the relevant Unicode characters for superscript letters, and their code points. In the hope that someone else will also find this useful, here they are.

Superscript letters in Unicode

Note that I’ve not included alternative forms, or forms with diacritics, in this list; neither have I listed letters in non-Latin alphabets, nor numerals. This list is based upon the very handy Wikipedia page on Unicode subscripts and superscripts which, although it focusses most on numerals, contains more information on all these subjects. Combining characters are shown with the dotted circle placeholder,  ◌ (U+25CC), to indicate placement. As always with Unicode, what you actually see will depend upon the capabilities of the fonts available to you.

Notes

  1. Cf. the feminine ordinal indicator, U+00AA, ª, in the Latin-1 Supplement code block, which may render with an underline, depending on font. []
  2. Cf. the masculine ordinal indicator, U+00BA, º, in the Latin-1 Supplement code block, which may render with an underline, depending on font. []
