It seems to be a good workaround for the hexl-mode because it won't break anything. So, I installed a proper change for that. Though, it doesn't solve the generic problem of "how to handle the case that the program requests different encoding for arguments and file (or stdin)". I think we should solve it after the release. --- Kenichi Handa handa@m17n.org
