Ticket #2372 (Editor sometimes shows multibyte UTF-8 chars as two dots)

Browse Source 
Sometimes when text contain multibyte UTF-8 chars, editor shows two dots instead of some letter.
When moving text cursor after that letter it will be displayed properly.
When moving cursor back (before letter) it will be displayed again as two dots.
