Re: Bug printing string where the 128th char is multibyte
Using the %s didn't solve the problem:
erdavila@antares ~/perl/feedbacks
$ cat BUG.c
#include <stdio.h>
int main() {
const char * str =
"0123456789" // 0 - 9
"0123456789" // 10 - 19
"0123456789" // 20 - 29
"0123456789" // 30 - 39
"0123456789" // 40 - 49
"0123456789" // 50 - 59
"0123456789" // 60 - 69
"0123456789" // 70 - 79
"0123456789" // 80 - 89
"0123456789" // 90 - 99
"0123456789" // 100 - 109
"0123456789" // 110 - 119
"0123456ç89" // 120 - 127
;
printf("%s", str);
return 0;
}

$ gcc -Wall BUG.c -o BUG

$ ./BUG
