OMG, multibyte decimal character! Does that occur anywhere other than Arabic? And even with Arabic, would it actually be seen in a sane locale setting on a contemporary computer? IMO the practical case is translating between monobyte '.' and ',', which is easy. Exotica could be dealt with as needed via very careful programming (strlen(localeconv()->decimal_point)).
