OS:                Linux

Desktop search results always empty is the search keyword contains Cyrillic symbols both for name search and for content search.

Also, if I make some comments to file (in Dolphin), after reopening these comments I see "?" instead of Cyrillic symbols.

The search by Latin-symbols keywords work right. The comments to files written in Latin symbols are displayed properly.

Reproducible: Always

Steps to Reproduce:
1. Make a file with text containing Cyrillic symbols/words.
2. Give strigi to index it.
3. Try the search with the keyword containing Cyrillic symbols/words.
OR
1. Enter Dolphin
2. Leave comments to file. Comments must contain Cyrillic symbols/words.
3. Reenter the comments.

Actual Results:  
Desktop search shows empty results if keyword contain Cyrillic symbols/words.
Comments to file contain "?" instead of Cyrillic symbols.

Expected Results:  
The desktop search should return results to Cyrillic symbols containing keywords.
The comments to files must contain Cyriilic symbols instead of "?"
