Str.strncasecmp

Warning g_strncasecmp has been deprecated since version 2.2 and should not be used in newly-written code. The problem with g_strncasecmp() is that it does the comparison by calling toupper()/tolower(). These functions are locale-specific and operate on single bytes. However, it is impossible to handle things correctly from an I18N standpoint by operating on bytes, since characters may be multibyte. Thus g_strncasecmp() is broken if your string is guaranteed to be ASCII, since it's locale-sensitive, and it's broken if your string is localized, since it doesn't work on many encodings at all, including UTF-8, EUC-JP, etc. There are therefore two replacement functions: g_ascii_strncasecmp(), which only works on ASCII and is not locale-sensitive, and g_utf8_casefold(), which is good for case-insensitive sorting of UTF-8. A case-insensitive string comparison, corresponding to the standard strncasecmp() function on platforms which support it. It is similar to g_strcasecmp() except it only compares the first n characters of the strings.
