This is just an experimental hack and cannot happily be merged into the upstream. Zsh's line editor apparently needs a rewrite in order to support multi-byte encodings because it strongly relies on the single-byte character scheme. These patches are mostly based on the work by ono@ono.org (Thanks!): http://www.ono.org/software/zsh-euc/ What I did over this is disable the hack for non-EUC locales. Maybe the patches can be moved to shells/zsh in the future, but it's premature for the moment. Notes: - forward-char, backward-char and backward-delete-char with no numeric argument should work properly with this hack. - Completion and redisplay should work fine. - There can be some trivial side-effects. - JIS X0201-Roman and JIS X0208-Kanji are supported. - JIS X0201-Katakana and JIS X0212 Kanji are NOT supported. - Only tested with the EUC-JP (ja_JP.eucJP) locale. I'm not sure if it works for GB 2312/CNS 11643-1/KS X 1001. Any feedbacks is welcome, especially a patch if it does not work. :)
