UTF8 bug with sha1_sum/md5_sum

[Valuyskiy Alex]

I can not use cyrillic (or another non-latin symbols) words for these methods: sha1_sum/md5_sum.

When I use they I see a bug: Wide character in subroutine entry at /usr/local/share/perl/5.14.2/Mojo/Util.pm line 262.

Also, why non-lating symbols display incorrectly on an error pages? http://prntscr.com/17vlug

It is because functions from Digest::* modules doesn't support wide characters.
You need to convert your string to bytes:

use Encode qw( encode_utf8 is_utf8 );
my $source_string = "...";
my $suitable = is_utf8( $source_string ) ? encode_utf8( $source_string ) : $source_string;
..now you can get SHA1/MD5/... from $suitable

BTW, there is an exellent description of Perl's unicode stuff in Russian: http://habrahabr.ru/post/53578/

What about the second question?

[Alexandre Zaitsev]

The problem is almost similar. Mojolicious uses Data::Dumper to generate exception pages. And Data::Dumper displays utf8-encoded strings in it's hexademical representation. If your data in stash hadn't been encoded in utf8, you would have got 'normal' symbols in dumper output. But I don't know easy solution in this case -- I suppose, you can't control where you'll get an exception to be able to convert your data in stash just before rendering :-)
There is another way -- you can create your own exception page (name it as "exception.html.ep" and put into your templates directory), where you can dump stash values using YAML, for example, that doesn't have such problems.

BTW, if you need to dump non-latin data correctly (i.e. human-readable) using Data::Dumper or Data::Dumper::Concise, you have to redefine qquote somewhere in your code, like this:

use Data::Dumper::Concise;

$Data::Dumper::Useqq = 1;

{ no warnings 'redefine';

    sub Data::Dumper::qquote {

        my $s = shift;

        return "'$s'";

    }

}

I've seen this hack somewhere on perlmonks. This way, Dumper will not escape non-latin thus they will be shown in human-readable form.
