I was able to fix this problem by doing the following:
adding the following line

$sluglist=str_replace("%","%%",$sluglist);

into lib/tags.php, just prior to
$term_ids = $wpdb->get_col( $wpdb->prepare("SELECT term_id FROM $wpdb->terms 
WHERE slug IN ($sluglist) ORDER BY term_id ASC "),0);

The source of the problem lies in the way wpdb object treats "%" signs in it's 
queries. If you want it to be literal, and not a template for substitution, you 
have to double it.
You can check the results here (you have to able to read Russian, though :)):

(page with tag cloud)
Example of search-by-tag page:
http://home.khris.net/?page_id=1640&gallerytag=%D1%86%D0%B2%D0%B5%D1%82%D1%8B
(this gallery tag means "flowers" in Russian)

I just tested the proposed change and it does fix the problem for unicode 
characters. 

I created some tags with a % in and some slugs in Cyrillic. In case I chose a 
Cyrillic tag I would get images the images with the tag with a % in as well.

I think this can be safely added to the code. I also created a patch file out 
of the patch from mrskh.
