CJK Input

Maybe a stupid question but yet I haven't find the right answer. I installed CJK on my system and tested e.q. the Wadalab tex-files. Everything went well (I can LaTeX the file, see the Kanji on the screen etc.). If I edit the file with xemacs, I only see the strange numbers like $B? etc., even if I start the environment as described in the CJK-Manual. If I enter Japanese text inside xemacs, I can see the Kanji clearly. But if I save and LaTeX the file everything is gone (empty space). I am sure that I am doing something wrong (maybe inside xemacs), but I haven't found yet the right hint. Thanks for any help in advance. By the way: We can't I see the New Years Greetings in KMail ? 新年おめでごさいま。 Best regards Ulrich Groh
