diacritics deploying Java EE app

Question

I have an app that is sending mail via GlassFish JavaMail Session.

I have localhost and production server, when I deploy the app on localhost - development - everything is ok, but on production, the letters in the e-mail with diacritics are not displayed properly, but as ??? question marks. The acute letters works: áéóíú , but the caron ščřďťňž don't. Do you know where I should start to find the solution? Both are linux machines - one is Arch the other Debian.

也许在一台机器上的编码是utf-8，而另一台是例如iso-8859-1？
