--- Comment #2 from Jan Turoň <janturon at email dot cz> ---
setlocale does some change, but still not right:
My system locale is cs_CZ, the default codepage is 1250, console uses 852. I
Have these results, considering this code:
const char *str = "ř";
mbtowc(&(a.w), str, 6);
printf("\na = %hhx%hhx", a.bytes.b2, a.bytes.b1);
setlocale(LC_CTYPE,"C"); // gives 0c5
setlocale(LC_CTYPE,"Czech_Czech Republic.1250"); // (same as "") gives 139
setlocale(LC_CTYPE,"Czech_Czech Republic.852"); // (same as "") gives 253c
The expected result is 159 (Unicode number of "ř").
