Erm... but the resposibilty is on the side of the party which fills
|struct lconv|, right ? AFAIK it should work like this: If |struct
lconv| contains multibyte characters then the consuming application
should output |decimal_point| and |thousands_sep| that way... or not ?
BTW: Would it be usefull to split the current locale into
1) ar_SA.UTF-8 (uses ASCII characters for |decimal_point| and
|thousands_sep|)
and
2) ar_SA.UTF-8 at ar_numeric (uses multibyte characters (to represent these
characters as arabic (multibyte) characters) for |decimal_point| and
|thousands_sep|)
