It was reported as a bug, but it isn't fixed now...X-( http://sourceware.org/bugzilla/show_bug.cgi?id=4335 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=471021 > If you think you can get your proposal passed "up-stream", > go ahead and try it, please! If you succeed, everything is fine. Hmmm, I think that you have misunderstood something because my explanation is bad. I called "up-stream" as the maintainance team of each OS, library, or application. I don't think that there is something single "up-stream". Japanese language users have tried to fix of the problem for many years, but it doesn't progress so much now. >> - In NetBSD, the change to which wcwidth of East Asian Ambiguous Characters >> returns 2 by CJK locale is planned. > So the same issue (of compliance and portability, especially in the > remote case) should be discussed in the NetBSD community. > (Is there a suitable forum or mailing list to check?) Sorry, I don't know it because I was personally advised by one of the NetBSD maintainer ( http://www.hi-matic.org/ (written in Japanese) ). >> I think that ALL locale implementations should treat East Asian >> Ambiguous Character Width as 2 for CJK locale. > Again, I agree that IF you manage to get ALL implementations to follow > this approach, the solution is fine. Please go ahead. I will do so, but I want to solve the problem on Cygwin first of all. >> How to detect it? The application using wcwidth is not necessarily >> executed with terminal emulator.

(like 'indent' command) I hope the following two results become the same. - the auto-format filter program using 'wcwidth'. - run auto-format command on editor.
