Re: LibXML and %ENV in 5.18 on Windows

I'm guessing this maybe unicode related, try adding

my $name = $attr->getValue();

use Devel::Peek;
Dump($name);
$name = Encode::encode( 'latin1', $name );
Dump($name);

or just

my $name = $attr->getValue();
$name = substr($name,0);

It is interesting to note that a Devel::Peek::Dump done in 5.16 also shows UTF8, but 5.16 does not have the problem that 5.18 does.

This is very helpful. Thank you! Any idea if this has been (or should be) reported as a BUG?	[reply]

Thank you. That page indicates v5.16.0 took an approach (assumes byte strings) that seems to work for me. My quandary is wondering why 5.18 then stops working for me. It SEEMS to me like a bug was introduced in 5.18. Could anyone look into this possibility (using my code as the test case)? Thanks!	[reply]
