tags in non-ascii are not displayed in url

Hello,
if I add a tag for an item in a non-ascii name /in russian/, the tag is not displayed in the URL, but only the id in the form of: site.tld/category/1.html. How to fix it so that it will be displays correctly in form: site.tld/category/1-tag-in-non-ascii.html?

Thanks

Hello,

Where do you get this link

The tag links from (a) tags cloud module and (b) tags field, should display unicode aliases

so verify the aliases of your tags

NOTE: i have found that the
print link and pagination links of the tags view do not add the unicode alias, will be fix in next release

Regards
