Tagging does not work with other languages tags (eg greek or russian)

discussions/tagged&Tag=Δοκιμή
Clicking on tag "Δοκιμή" displays an empty result because it does not recognise the encoding

(message displayed is Questions tagged with '')

I think this problem is similar with this : http://vanillaforums.org/discussion/12703/utf-8-tagging

which haven't been solved.
Even in Issue tracker it has no comments...
Thanks

The problem is caused from the Tagging plug-in
1. class.tagging.plugin.php uses strtolower which does not support UTF-8 so your Unicode data are not stored in the database.
A solution to problem(1) is to use mb_strtolower() (which handles Unicode but is slower) :
replace :
$FormTags = trim(strtolower(GetValue('Tags', $FormPostValues, ''))); //ORIGINAL line 148

with

$FormTags = trim(mb_strtolower(GetValue('Tags', $FormPostValues, ''), 'UTF-8')); //mod by trister

and

'Name' => strtolower($NewTag), // ORIGINAL line 166 (I Think)

with

'Name' => mb_strtolower($NewTag, 'UTF-8'), //mod

2. The second problem is the URL creation of the PopularTag module (class.tagmodule.php) and is cause by this statement
if (urlencode($Tag->Name) == $Tag->Name) .
My modification (don't know if it causes any problem -I don't have any problem so far) actually disables this if statement :
replace line 61

echo Anchor(htmlspecialchars($Tag->Name), 'discussions/tagged?Tag='.urlencode($Tag->Name)); //ORIG line

with

echo Anchor(htmlspecialchars($Tag->Name), 'discussions/tagged/'.urlencode($Tag->Name));// mod

Tags should now be working...
If you encounter any problem please post it here. If I find it works ok I'll make a modified Tagging plug-in and post it here.
