Re^4: Help for "Cannot decode string with wide characters..." and CGI.pm

I get it, that strings shall not be double decoded. I got it to work without errors, but I do not get the UTF-8 displayed.

print $q->header(-charset => 'utf-8');
my $val = $q->param('key');
print utf8::is_utf8($val); exit;

This test gives me 1, which means, the value is UTF-8. But the value is not correctly displayed, just strange signs. Do you know what to do?

Do you know what to do? verify everything :) all this encoding/decoding stuff just makes sure the bytes sent are proper, it doesn't ensure the HTML/HTTP is interpreted as utf You say some browsers are not displaying what you want?
