* stringprep_locale_charset:
*
* 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 preffered 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.

*
* Note that this function return what it believe the SYSTEM is using
* as a locale, not what locale the program is currently in (modified,
* e.g., by a setlocale(LC_CTYPE, "ISO-8859-1")). The reason is that
* data read from argv[], stdin etc comes from the system, and is more
* likely to be encoded using the system locale than the program
* locale.
*
* You can set the environment variable CHARSET to override the value
* returned. Note that this function caches the result, so you will
* have to modify CHARSET before calling (even indirectly) any
* stringprep functions, e.g., by setting it when invoking the
* application.
*
* Return value: Return the character set used by the system locale.
* It will never return NULL, but use "ASCII" as a fallback.
