Views with taxonomy contextual filter not working in Russian language in Drupal 7 I have a View which works perfectly in English. 
It has a contextual filter, with options 
Content: Has taxonomy term ID , 
filters by taxonomy term with term name converted to term Id. 

But when I put in the URL the term in Russian, Раздел, it does not show the content. 
When I check the SQL, to my surprise and dismay, this is what I find: search_index.word = 'razdel'. 

Clearly there has been a transliteration. Maybe this is why it does not work. I do not really what to do.
It's probably the collation of your fields and tables in database, try to check to see if all the tables collation is set to utf8_general_ci

you can google to find an script to bulk update your tables and or fields collation
