DESCRIPTION

17       Enumerated  return codes of the TLD checking functions.  The value 0 is
18       guaranteed to always correspond to success.
19
20
21       Find out current locale charset.  The function respect the CHARSET  en‐
22       vironment  variable, but typically uses nl_langinfo(CODESET) when it is
23       supported.  It fall back on "ASCII" if CHARSET isn't set  and  nl_lang‐
24       info isn't supported or return anything.
25
26       Note  that  this  function  return the application's locale's preferred
27       charset (or thread's locale's preferred charset, if your system support
28       thread-specific  locales).   It  does not return what the system may be
29       using.  Thus, if you receive data from external sources you  cannot  in
30       general  use this function to guess what charset it is encoded in.  Use
31       stringprep_convert from the external representation  into  the  charset
32       returned by this function, to have data in the locale encoding.
33
34       Return  value: Return the character set used by the current locale.  It
35       will never return NULL, but use "ASCII" as a fallback.
