Java SE (Java Platform, Standard Edition)

Hi there,


I made some (file text encrypting) application. I wanted to launch it on few OS. Text processing looks this:

JTextArea -> String -> base64 (with UTF-16BE or UTF-32BE) -> DES/MD5/other -> bytes array -> file

The problem is when I move this encrypted file to another OS insted of proper characters I get invalid signs.

For example:
[Windows 7 x64 (everything OK)|http://ifotos.pl/zobacz/Windows7-_rhpxhpq.jpg/] -> [Windows XP SP3 x32/x64 (almost all special characters are invalid)|http://ifotos.pl/zobacz/WindowsXP_rhpxhrq.JPG/]

Windows 7 x64 -> Linux (ubuntu) (some characters are invalid, but not many of them)

Windows 7 x64 -> MacOS (Leopard) (everything is OK)


I think the problem involves characters encoding. I don't know why but under Windows XP almost all special characters are invalid. Can someone tell me why and how to fix it?

I checked the default charset of this Java virtual machine under Windows XP SP3 x32:

Charset.defaultCharset()
Charset.availableCharsets() 

Default charset is:   windows-1250


Available charsets are:
