stringprep_locale_charset - API function
const char * stringprep_locale_charset( void);
Enumerated return codes of the TLD checking functions. The value 0 is
guaranteed to always correspond to success.
Find out current locale charset. The function respect the CHARSET
environment variable, but typically uses nl_langinfo(CODESET) when it
is supported. It fall back on "ASCII" if CHARSET isn't set and
nl_langinfo isn't supported or return anything.
Note that this function return the application's locale's preferred
charset (or thread's locale's preferred charset, if your system support
thread-specific locales). It does not return what the system may be
using. Thus, if you receive data from external sources you cannot in
general use this function to guess what charset it is encoded in. Use
stringprep_convert from the external representation into the charset
returned by this function, to have data in the locale encoding.
Return value: Return the character set used by the current locale. It
will never return NULL, but use "ASCII" as a fallback.
