Guild Wars 2

Client crashes whenever I try to send a mail with a SUBJECT containing my native language “lithuanian” characters:
http://www.likit.lt/all/Testai/1-5/abc.gif
Posted an IMAGE link with the characters because the forum doesn’t seem to allow to enter it… works on preview but does not work on submit.
A friend tried it too and his client crashed aswell
As test words I used “Anglies r?da” (eng. translation “Coal Ore”) and it crashed
Sometimes it crashes without even sending(it only takes to enter words into the subject line) but if I manage to send the person gets the mail, just the senders client crashes

Same thing with chat. Client crashes when you use Lithuanian characters, but it’s random. I’ve tried writing same words after crashes and nothing happened. Here’s Lithuanian specific characters: ?, ?, ?, ?, ?, š, ?, ?, ž, ?, ?, ?, ?, ?, Š, ?, ?, Ž.

Edit:
ok, that’s strange, forum shows characters in “preview post”, but not after actually posting..
