utf8

Afficher les obsolètes

This library provides basic support for UTF-8 encoding. This library does not provide any support for Unicode other than the handling of the encoding. Any operation that needs the meaning of a character, such as character classification, is outside its scope.

Unless stated otherwise, all functions that expect a byte position as a parameter assume that the given position is either the start of a byte sequence or one plus the length of the subject string. As in the string library, negative indices count from the end of the string.

You can find a large catalog of usable UTF-8 characters here.
