#10 Incorrect Russian 'ё', 'й', etc. letters display

[v_2e]

Hello!
I have encountered a strange behaviour of Beaver on my machine. When I start Beaver and edit a new file, everything looks Ok, but when I open a previously saved file containing some Russian text, all the letters like 'ё', 'й', etc. are displayed incorrectly. I believe, this problem happens not only with Russian text, but with some other symbols having something above the letters.

Same problem here with German Umlaute, using version 0.4.1, I attached a screenshot.
