Dear Developers,
After sending out several gabaged chinese mail I findout that XEmacs
always using a so called `undecided' encoding system to open
empty-existed-file(and maybe only this kind of files).
IMO it should use a user defined encoding system or inherent the
current environment locale encoding system to do that.

Maybe in general, but definitely not in a mail program. For example,
in Japan the standard mail encodings are ISO-2022-JP and UTF-8, but
most OSes (except Linux) have the locale ja_JP.eucJP or (implicitly)
ja_JP.shift_jis. The mail program should be dealing with this
explicitly. Fix your mail program.

Err... Sorry, that is not the point I want to express. I do can do some
tricky to work around this issue, but, I think the strange behavir is inidcating
a exsit bug. to reproduce:
1. open a XEmacs session
2. C-x C-f non-exist.file
=> buffer `non-exist.file' is using your locale encoding.
3. type something(even a single `a' is okey) into `no-exist.file' and C-x C-s, C-x
C-k <RET>
4. C-x C-f non-exist.file
=> buffer `non-exist.file' is using your locale encoding.
5. delete all the `non-exist.file' content and C-x C-s, C-x C-k <RET>
6. C-x C-f non-exist.file (it is now a kind of empty-exist-file now).
=> buffer `non-exist.file' is using `undecide' encoding system(modeline
indicator `AUTO')
I think it use same encoding system as open a new-nonexist-file or nonempty-exist-file.

Yes, I admitted that there may be a bug in XEmacs. I don't intend to
do anything about it in the near future, because I believe that code
needs to be redone from scratch. In particular, I think the coding
system for files should be decided at *write* time, not *read* time,
in which case we'll end up changing it back to 'undecided.

I think it sould use same encoding system as when it open a new-nonexist-file or
nonempty-exist-file does.
