ASCII Character º
Masculine ordinal indicatorIn 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. In Spanish, Portuguese, Italian, and Galician, the ordinal indicators º and ª are appended to the numeral depending on whether the grammatical gender is masculine or feminine. The Romance feminine and masculine ordinal indicators were adopted into the 8-bit ECMA-94 encoding in 1985 and the ISO 8859-1 encoding in 1987, at positions 170 (xAA) and 186 (xBA), respectively.
