I use korean username for CVS user.
When I use korean CVS username with IntelliJ,
It displays "unknown user or bad password".
But with Tortoise CVS, It works good.
So I decompile PServerConnection.class in javacvs.jar and
javacvs.jar uses java.io.Writer class for sending and receiving data.
When I replace Writer with OutputStream, It works good.
But many part of javacvs.jar uses Writer class and this
will break multi-lingual files or image files.
How can I solve this?
