     This information is retrieved by nl_langinfo(3C).

     The items CRNCYSTR, RADIXCHAR, and THOUSEP are extracted from the fields
     currency_symbol, decimal_point, and thousands_sep in the structure
     returned by localeconv(3C).

     The items T_FMT, D_FMT, D_T_FMT, YESSTR, and NOSTR are retrieved from a
     special message catalog named Xopen_info which should be generated for
     each locale supported and installed in the appropriate directory (see
     mkmsgs(1) and gettxt(3C)).  This catalog should have the messages in the
     order T_FMT, D_FMT, D_T_FMT, YESSTR, and NOSTR.

     All other items are as returned by strftime(3C).
