Subject: UTF-8 Issues with Class::Std (possible broken Perl)
Hi Damian, I'm sure this is not a bug with Class::Std, but that's where it is manifesting, and I really want to use Class::Std, so I'm hoping you can give me some clues as to how to fix it. I'm seeing (apparently) utf-8 related problems with using Class::Std. The perl version is that which comes with Red Hat Enterprise Linux 3. For example ...

Might be a bug in 5.8.0 or an endianness issue. Try removing the line: | :$key« \s* ([^»]*) \s* » and see if that solves your problem. Damian

Removing this line does indeed solve the problem. Is this going to break/restrict any functionality in Class::Std (I'm sure it was there for a purpose)? Here's some more info that may or may not be relevant ... Here's some more info that may or may not be relevant (using the unmodified package) ...

It's going to mean you can't use Perl6ish double angles on :init, :default_val, etc. specifications within an :ATTR. No great impediment, I suspect. A better alternative than removing the line might be for you to simply replace it with: | :$key\x{AB} \s* ([^\x{BB}]*) \s* \x{BB} Damian

Your new suggestion works fine. Does this mean there is something broken with our Perl, or do we need a later version? Obviously we would prefer to be using the 'vanilla' Class::Std rather than our own hacked version. Regards, Steve

I'm not sure. 5.8.3 on MacOS handled it fine. But that may have been the MacOSity, not the 5.8.3ity. Show quoted text

When the next release goes out, that "hack" will become the "vanilla". All the best, Damian
