U+00BF Inverted Question Mark
U+00BF 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 Punctuation and is commonly used, that is, in no specific script. The character is also known as turned question mark.
The glyph is not a composition. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. U+00BF prohibits a line break after it.
The CLDR project calls this character “inverted question mark” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: inverted, mark, question.
The Wikipedia has the following information about this codepoint:
The upside-down (also inverted, turned or rotated) question mark ¿ and exclamation mark ¡ are punctuation marks used to begin interrogative and exclamatory sentences or clauses in Spanish and some languages that have cultural ties with Spain, such as Asturian and Waray. The initial marks are mirrored at the end of the sentence or clause by the ordinary question mark, ?, or exclamation mark, !.
Upside-down 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.
