[ID 20000316.001] UTF8-ness seems strange
Message ID:

This is a bug report for perl from gbarr@chipper.localdomain,
generated with the help of perlbug 1.27 running under perl v5.6.0.
-----------------------------------------------------------------
[Please enter your report here]
The setting of the UTF8 bit still seems strange.
Surley if a regexp is executed in a utf8 block then $1 etc
should be tagged as UTF8. Likewise if executed in a block
which explicitly hase use bytes.
Also split, if executed in a utf8 scope, should its results
not be utf8 strings ?
Graham.
use Devel::Peek;
$\ = "\n";
$x = v1.999;
print length $x;
{
use bytes;
print length $x;
($y) = ($x =~ /(.*)/s);
}
print unpack("H*",$x);
print "Should be UTF8 - OK";
print Dump($x);
print "Should not be UTF8 - OK";
print Dump($y);
{
use utf8;
print "Should be UTF8 - BAD";
print Dump(($x =~ /(.)/gs)[1]);
}
{
use utf8;
print "Should be UTF8 - BAD";
print Dump( (split(//,$y))[1]);
}
