KDE sometimes really have problems with file name encodings. There are several scenarios where this happens:
- Grab a file via scp from a remote location
- Grab a file from another media which uses a different encoding
- Grab a file via ftp with a different encoding
- ...

Now -- KDE doesn't copy the file at all and complains it does not exist. If you copy it via command line everything works fine but you can't even enter this new dir / open this new file on your local HD in dolphin although it works fine in the command line.

For instance:
I grabbed a dir from a windows box which I uploaded to my kubuntu box via winscp let's call it 'Krümel'.
Because of some encoding problems it is on my hard disk has 'Kr�mel' but I can't enter this dir. I get the error message 'The file or folder /home/roland/Kr�mel doesn not exist'

I really had many problems with that. As soon as different encodings are used chances are high things get messed up. I had those problems with different kio-slaves (smb, file, sftp, ...) and ALL kde 4 version I tried (4.1.x, 4.2.x, 4.3.x with kubuntu and gentoo).

If I can help any further to investigate this problem let me know.
