broken taxonomy url encodyng for international texts

Hi,

I had some problems today and it looks like I found solution.

The problem is that I have russian taxonomy terms. Default article page show everything right. When I select some category and follow via encoded link like http://chtivo.vl.ru/?q=article/%F0%9F%F1%80%F0%BE%F0%B7%F0%B0 I received right articles but category name looks terrible, only firsh symbol is correct. If i manually enter http://chtivo.vl.ru/?q=article/Проза, for example, then module show the same page, with correct category, and other url (Opera encoded when sending) http://chtivo.vl.ru/?q=article/%D0%9F%D1%80%D0%BE%D0%B7%D0%B0.

So... I searched through code and removed strtolower call in 237 string $cur->link = $parent_url . '/' . urlencode(strtolower(trim($cur->name)));

Now it works fine, hope nothing broken.

Regards,
Igor.
