So what's happening in the controller, that might change it?
Are you using commands or modules that work only with octets instead of UTF-8?
my $octets = encode("UTF-8", $utf8_string);
...converts UTF-8 to Octets.
my $utf8_string = decode("UTF-8", $octets);
...converts Octets to UTF-8.
I put...
use Encode qw(decode encode);
...at the start of my controller to use these functions.
My UTF-8 boiler plate for my Catalyst Controllers is:
#Always:
use strict;
use warnings;
use Moose;
use namespace::autoclean;
#UTF-8:
use utf8;
use v5.30;
use warnings (
'FATAL', #makes anything in this list fatal
'utf8', #utf8 is a warnings category.
);
#Specific:
use Encode
qw(
decode
encode
);
...and any other specific modules I need, I put in the specific bit.
The reason I use...
use v5.30;
...is because it enables for following features:
unicode_strings (auto-enabled with "use v5.12;" or higher),
unicode_eval (auto-enabled with "use v5.16;" or higher),
fc (auto-enabled with "use v5.16;" or higher).
I guess I could just use v5.16, haha.
I use v5.30 because it's fun to be working with the latest Perl, =).
There are two webpages I found useful for understanding Perl and Unicode:
https://stackoverflow.com/questions/6162484/why-does-modern-perl-avoid-utf-8-by-default/6163129#6163129
https://www.perl.com/pub/2012/04/perlunicook-standard-preamble.html/
However, I do not know if it is a Perl and Unicode issue.
It could be a MySQL issue,
it could be a really simple mistake somewhere in the code, etc,
it could be the other module you're using, etc.
Until you share more context,
it's difficult to know what the problem could be.
Even then, I'm not an expert at character codes, ^_^.
I do hope someone in this list can help you though,
and everything works out, =).

Hi,
I created a controller that requests data from a mysql database via another
module. The data in this case is a place in Germany called "Münster". In the
module that requests the data from mysql, with the mysql_enable_utf8 flag set
to 1, it is still correct just before it is returned to the catalyst
controller. But what it arrives in the controller someting has changed. The
original character values are:
77 - 252 - 110 - 115 - 116 - 101 - 114
But when they arrive in the controller it has changed into
77 - 195 - 188 - 110 - 115 - 116 - 101 - 114
And becomes unreadable. How do I handle this?

Kind regards
Theo
