º

The symbol º, ^o, or ^o, is a masculine ordinal indicator used to denote ordinal numbers in Portuguese, Spanish and Italian. The indicator is a superscript lowercase o, which is the masculine ending for an adjective in the three languages, and may be underlined. It is often confused with the degree symbol (°), but the border of the circle in the degree symbol has a uniform width while in most typefaces the sides of the indicator have a thicker border than the top and bottom. For example, 1^st (first) in English is written as 1º (primero).

The World Wide Web Consortium and the Unicode Consortium have deprecated the the use of the character º whenever superscript markup is available.[1] For example, in XHTML 12<sup>o</sup> should be used instead of 12º.
