Ah, right! Take a look into newlib/libc/locale/locale.c, function __loadlocale(). This function is called from _setlocale_r(). However, it calls __set_charset_from_locale() *only* if the charset isn't already given explicitely in the LC_* or LANG string, because otherwise we already know the charset, after all. Darn! That foils my plans for world domination... > Let me consider a while. Thanks, I'll do the same. I'd really like to simplify this stuff and doing the locale shuffle in two entirely different locations at different times is prone to getting out of sync. Corinna
