Steps to reproduce the problem:
1. Open page with long cyrillic title (e.g.http://www.science-education.ru/ru/article/view?id=22604 )
2. Press Ctrl-S to save page
3. Press save (or just take a look at supposed filename)

Alternative steps
1. Open any page
2. Press Ctrl-Shift-I to view its code
3. Replace title to some cyrillic text of length 250 or greater. 250th symbol should be cyrillic letter
(e.g.
"ааааааааа ббббббббб ввввввввв ггггггггг ддддддддд еееееееее жжжжжжжжж ззззззззз иииииииии ккккккккк ллллллллл ммммммммм ннннннннн ооооооооо" without quotes)
4. Press Ctrl-S
5. Press Save

What is the expected behavior?
There should not be any unprintable symbols in filename

What went wrong?
Supposed filename contains unprintable symbol (question mark in  a black square). Impossible to save page with that filename

Did this work before? N/A
