Problem with language-specific characters in segment

Hi to all!
I have a following problem with segment tool. In the output of segment appears <unk> token instead of words including language-specific characters - although in language model file they are saved correctly and input text file has the same coding (ISO-Latin 2) as the training text. 
 Does anybody know what's the problem?

Language model was buil using:
ngram-count -write-vocab vocabulary -text train2.txt -write probs -lm lmfile2

Segment tool was used with option:
segment -lm lmfile2 -text test3.txt -unk -posteriors -continuous

Disabling -unk option  I got right words in the output but posteriors are probably not correct.
