The -k option is only for 'add' and 'update' etc.
The default with the command-line client is to do ASCII and you need to explicitly do 'cvs add -kb' for images, and jar files, etc....
Note also that the binary -kb flag is set automatically when adding certain file types, based on patterns defined in CVSROOT/cvswrappers (which we cannot change, belongs to the cvsadmin group).
I knew this setting, but this is not the problem of our binary adds as only few and really binary file endings are set there.
I might be wrong but today I had the feeling that Eclipse just ignores the default -kkv set in Eclipse itself and adds every file with unknown file ending as binary. You maybe have to add your file endings at "Window > Preferences > Team > File Content".
