After Yong Li's comment on this issue, I gave it another try, and it works, well, partially. After modifying the /usr/lib/im/htt.conf file, I can finally type Hiragana within gedit, but I can't convert it to Kanji. When I do Ctrl-space and type a-k-a, and I hit space, nothing happens. Then I see these entires in /var/log/messages Mar 1 08:40:22 hydro htt_server[19364]: Invalid message(IC normal state):43 Mar 1 08:40:35 hydro htt_server[19364]: Invalid message(IC normal state):73 Mar 1 08:40:35 hydro htt_server[19364]: Invalid message(IC normal state):73 Mar 1 08:40:37 hydro htt_server[19364]: Invalid message(IC normal state):13 Mar 1 08:40:37 hydro htt_server[19364]: Invalid message(IC normal state):13 Mar 1 08:40:37 hydro htt_server[19364]: Invalid message(IC normal state):73 Mar 1 08:40:37 hydro htt_server[19364]: Invalid message(IC normal state):43 Mar 1 08:40:53 hydro htt_server[19364]: Invalid message(IC normal state):43 Mar 1 08:40:59 hydro htt_server[19364]: Invalid message(IC normal state):73 Mar 1 08:40:59 hydro htt_server[19364]: Invalid message(IC normal state):43 Mar 1 08:41:16 hydro htt_server[19364]: Invalid message(IC normal state):13 What I *can* do is convert Hiragana to Katakana by hitting the arrow-down key. This works as expected. I also tried with LANG=zh_CN.UTF-8. Now this seems to work just fine. I've typed several Chinese characters in simplified Chinese, and it works flawlessly. Hmm.. This makes me jealous. ;) Kohei
