Keith,
what do you see with this testapp? I get an ugly dotted square, which
usually confuses copy&paste into a bugzilla. Also the mirroring between
various bugzilla screws it up even more. All output should be either
plain ASCII or UTF-8. I'm sure kdb should not care about any locale
other than ASCII, so its better to just mask the non-printable bytes.
#include <stdio.h>
int main(void)
{
unsigned char buf[2];
buf[0] = 0xc0;
buf[1] = '\0';
printf("%s\n", buf);
return 0;
}
The kernel considers 0xc0-0xff as printable chars, this leads to
binary garbage. Just mask it to ASCII.
