--- Comment #3 from Petr Pisar <ppisar@???> ---
And isprint() has undefined behavior on values that cannot be represented in
unsigned char although the argument has type int. This is defined by ISO C and
POSIX. See similar bug report
<https://bugzilla.redhat.com/show_bug.cgi?id=189525>.

One should use iswprint() instead probably. But that requires conversion to
wchar_t.
