Am I doing something wrong or is this a bug:
use strict;
my $p;
foreach $p (qw (C U C))
{
my $s = pack($p, 200);
print "pack('$p', 200): is_utf8=" . (utf8::is_utf8($s) ? 'yes' : 'no ')
. "\t$s\t" . join(',', unpack('C*', $s)) . "\n";
}
Generates the following output:
pack('C', 200): is_utf8=no « 200
pack('U', 200): is_utf8=yes « 195,136
Wide character in print at T:\test2.pl line 8.
pack('C', 200): is_utf8=yes « 200
Specifically, the first and last ought to be the same, and I shouldn't be
getting that error.
Seen on perl 5.8.3, 5.8.6 and 5.8.7. E.g., my current perl -v:
This is perl, v5.8.7 built for MSWin32-x86-multi-thread
(with 7 registered patches, see perl -V for more detail)
This is fixed in the development branch of perl (5.9.x).
Something probably goes wrong with the localisation of UTF-8 magic.
The next 5.8.x release may have this bug fixed.
