       bind_textdomain_codeset - set encoding of message translations


       char * bind_textdomain_codeset (const char * domainname,
                                       const char * codeset);

       The  bind_textdomain_codeset  function  sets  the  output codeset for message catalogs for
       domain domainname.

       A message domain is a set of translatable msgid messages. Usually, every software  package
       has its own message domain.

       By  default,  the  gettext family of functions returns translated messages in the locale's
       character encoding, which can be retrieved as nl_langinfo(CODESET). The need  for  calling
       bind_textdomain_codeset  arises  for  programs which store strings in a locale independent
       way (e.g.  UTF-8) and want to avoid an extra character  set  conversion  on  the  returned
       translated messages.

       domainname must be a non-empty string.

       If  codeset  is  not  NULL,  it  must  be  a valid encoding name which can be used for the
       iconv_open function. The bind_textdomain_codeset function sets the output codeset for mes‐
       sage  catalogs belonging to domain domainname to codeset. The function makes copies of the
       argument strings as needed.

       If codeset is NULL, the function returns the previously set codeset for domain domainname.
       The default is NULL, denoting the locale's character encoding.

       If successful, the bind_textdomain_codeset function returns the current codeset for domain
       domainname, after possibly changing it. The resulting  string  is  valid  until  the  next
       bind_textdomain_codeset call for the same domainname and must not be modified or freed. If
       a memory allocation failure occurs, it sets errno to ENOMEM and returns NULL. If no  code‐
       set has been set for domain domainname, it returns NULL.

       The following error can occur, among others:

       ENOMEM Not enough memory available.

       The  return  type ought to be const char *, but is char * to avoid warnings in C code pre‐
       dating ANSI C.
