[Cgi-session-user] utf8 problem

[Thomas G. <tho...@pi...>]

Hi,

I'm having problems getting CGI::Session to work with utf8.
I read the "A Warning about UTF8" section but I couldn't find the 
following issue anywhere:

In my session I have utf8 encoded strings like 'jörg'.

The session data gets serialized by default serializer Data::Dumper into 
a MySQL data column (mediumtext, charset utf8, collation 
utf8_unicode_ci) as expected with utf8 characters escaped like this: 
'j\x{f6}rg'

Now, the problem is that when this session data get's thawed, the 
resulting string 'jörg' is missing perls utf8 flag. Which causes 
Data::Dumper to just cut the data at the utf8 character 'ö' during next 
freeze. Result: the dump is stored corrupted in the data column and 
Data::Dumper crashes of course when trying to thaw that next time.

I already posted this problem incl more details and code snippets at 
stackoverflow to no avail:

It looks like a bug to me but since I don't think that I'm the only one 
trying to use CGI::Session with utf8 characters I guess that I rather 
must be missing something here.

I'd be really grateful for any hints on this.

Best regards,
Thomas
