[Fontconfig] rendered texts are overlaping

[Arkadiusz Miśkiewicz]

Hello.

I'm trying to figure out why some fonts when being in use cause texts being 
overlaped. Often this happens with national characters.

Example, opening
http://fzs.sve-mo.ba/sites/default/files/dokumenti-vijesti/sample.pdf
in internal google-chrome 38 pdf viewer causes some text being rendered one on 
another, screenshots:

What could be reason for such behaviour? I have little knowledge in the area, 
so any information/hint is welcome, so I could experiment and narrow down 
possibilities.

fontconfig 2.11.1
freetype 2.5.3
