Hi folks. I'm interested in purchasing Sony reader, but as it looks, it's capable of reading only western texts? That's really bad news for me

Older Librie has been capable of reading both western and eastern texts. Could anyone, please, test the below two text files (both contains few Czech and Slovak characters) and if possible show me a screenshot? Thank you in advance!
