--- Comment #1 from Boris Egorov <ego...@linux.com> ---
I can reproduce it. It looks like the problem is in kcodecs.
UnicodeGroupProber::HandleData has this code:
if (4 >= aBuf[1] && aBuf[1] >= 0 && isprint(aBuf[0])) {
where isprint is a macro:
enum {
// non-relevant
CTYPE_PRINT = 1 << 6,
// non-relevant
};
#define ctype_test(c, t) ((ctype_data[(unsigned short)c] & t) != 0)
#define isprint(c) ctype_test((c), CTYPE_PRINT)
And sometimes aBuf contains negative values. So we got an out-of-bounds index
for ctype_data array: c is negative in "(unsigned short)c".
I don't know what to do with this, but I think it is a kcodecs bug.
