U+00AA Feminine Ordinal Indicator
U+00AA was added in Unicode version 1.1 in 1993. It belongs to the block Latin-1 Supplement in the Basic Multilingual Plane.
This character is a Other Letter and is mainly used in the Latin script.
The glyph is a superscript version of the glyph Latin Small Letter A. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it is written from left to right. When changing direction it is not mirrored. If its East Asian Width is “narrow”, U+00AA forms a word with similar characters, which prevents a line break inside it. Otherwise it allows line breaks around it, except in some numeric contexts.
The Wikipedia has the following information about this codepoint:
In written languages, an ordinal indicator is a character, or group of characters, following a numeral denoting that it is an ordinal number, rather than a cardinal number. Historically these letters were "elevated terminals", that is to say the last few letters of the full word denoting the ordinal form of the number displayed as a superscript. Probably originating with Latin scribes, the character(s) used vary in different languages.
In English orthography, this corresponds to the suffixes ‑st, ‑nd, ‑rd, ‑th in written ordinals (represented either on the line 1st, 2nd, 3rd, 4th or as superscript 1st, 2nd, 3rd, 4th). Also commonly encountered in Romance languages are the superscript or superior (and often underlined) masculine ordinal indicator, º, and feminine ordinal indicator, ª. In formal typography, the ordinal indicators ª and º are distinguishable from other characters.
The practice of underlined (or doubly underlined) superscripted abbreviations was common in 19th-century writing (not limited to ordinal indicators in particular, and extant in the numero sign №), and was found in handwritten English until at least the late 19th century (e.g. first abbreviated '1st' or 1st).
