The Wikipedia has the following information about this codepoint:

The inverted question mark, ¿, and inverted exclamation mark, ¡, are punctuation marks used to begin interrogative and exclamatory sentences or clauses in Spanish and some languages which have cultural ties with Spain, such as Asturian and Waray languages. The initial marks are mirrored at the end of the sentence or clause by the 'ordinary' question mark, ?, or exclamation mark, !.

Inverted marks are supported by various standards, including ISO-8859-1, Unicode, and HTML. They can be entered directly on keyboards designed for Spanish-speaking countries.
