Hi,
I found a problem in the generation of aliases for items and categories.
I had a "à" in my title. The result: the alias cut before "à".

To fix this, I edit two files:
administrator/components/com_k2/tables/k2item.php line 71
administrator/components/com_k2/tables/k2category.php line 46

After mb_internal_encoding("UTF-8");
Add mb_regex_encoding('UTF-8');

Versions:
- K2 2.0 build 20090806
- Joomla 1.5.14
- Apache 2.2.11
- PHP 5.2.9-2
- MySQL 5.1.33

Hi. This has been fixed for the next release. Thank you for reporting this issue to us.
