Editing Ordinal indicator (section)

==Encoding==
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 (both based on [[Digital Equipment Corporation|DEC]]'s [[Multinational Character Set]] designed for [[VT220]]), at positions 170 (xAA) and 186 (xBA), respectively. ISO 8859-1 was incorporated as the first 256 code points of [[ISO/IEC 10646]] and [[Unicode]] in 1991. The Unicode characters are thus:
* {{unichar|00AA|FEMININE ORDINAL INDICATOR|html=}}
* {{unichar|00BA|MASCULINE ORDINAL INDICATOR|html=}}

There are [[Unicode subscripts and superscripts|superscript versions of the letters {{angbr|a}} and {{angbr|o}} in Unicode]]; these are different characters and should not be used as ordinal indicators.

The majority of character sets intended to support Galician, Portuguese, and/or Spanish have those two characters encoded in hexadecimal as follows:
