| Subject: | XML::Dumper incorrectly treats byte data |
Starting with Perl 5.6, all string scalars inside Perl have an "utf-8
bit" attached to them, indicating whether the string is to be
interpreted as a string of bytes or a string of text (look for "How Do I
Know Whether My String Is In Unicode?" in perluniintro). XML::Dumper
should attempt to serialize and restore this bit, using a new attribute
to <item> e.g. <item bytes="1">.
Right now, t/11_control_characters.t seems to imply that XML::Dumper
simply tries to weed out control characters, which means that objects
with byte data in them cannot round trip.
