Handyman... it should have support for full UTF-8
The problem is the URL converts unique characters to URL encoding.
So if you can allow it to decode the URL, then I think it will bypass any problems.

[Handyman]

OH... yeah... let me try and fix some UTF-8 stuff.

[Handyman]

Whew... after much testing, I came up with this
Replace the format_url in functions.php with this

All that does is if the string needs a special utf8 character, it changes it to a random letter or number.
I tested it with Chinese characters

There's probably a better way to do this... but that will work for the moment.

Zip updated with the fixes posted above.

#
#-----[ REPLACE WITH ]----------------
#
REPLACE WITH
'U_VIEW_FORUM' => append_sid("{$phpbb_root_path}f" . $forum_id . format_url($topic_data['forum_name'])),
#

What's wrong with that line?

Faster version of assign_rand_value($num) function:

Spoiler:

Code: Select all

<?php
// @param int 1 - 36
function assign_rand_value($num)
{
$values = array('a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', '0', '1', '2', '3', '4', '5', '6', '7', '8', '9');
return $values[$num - 1];
}
