title: Incorrect placement of accent mark on site with UTF8 encoding (wth cyrillic words only)
body: <p>I am developing webpage with contains some cyrillic text with stress marks. To place stress mark I use utf8 character U0301 (COMBINING ACUTE ACCENT). In every editor I have already used and every cyrillic-related webpage I have already seen this stress mark is displayed above letter which is placed <em>before</em> this character in the text. My problem is that on my page this character is displayed above letter which is placed <em>after</em> this mark in text. What is more this incorrect behaviour can be observed only on cyrillic words. With usual latin words it is displayed correctly.</p>
  
  <p>I set every encoding-related headers.</p>
  
  <p>[EDIT]</p>
  
  <p>This issue seems to be present on Firefox only (I use version 13.0.1). When I use Chrome then accent marks are displayed correctly.</p>
