Have you tried to set the buffer encoding to Chinese once you have
opened the file? Something like "C-x <RET> r chinese-iso-8bit <RET>" (or
whatever coding system you prefer)

Hmm, hard for me, I don't use Chinese at all.

Which Emacs/Tramp versions are you using? And do you have an example
file I could use for testing? Please tell me also, which coding system I
shall use.

Best regards, Michael.

Are you using ftp, and if so, is it in binary mode?

I assume you can open the file correctly if you copy
it to your local machine.

What happens on the remote host, when you apply

/bin/ls -al /path/

(assuming, that you have created /path/你好 )

Is this on the local or the remote host?

Same here. However, if I open /ssh:host:/path/你好/ I can continue to
work. So it seems to be a problem of /bin/ls

I don't use tramp from remote, just as a convenience for su.
(require 'tramp)
(setq password-cache nil
      tramp-default-method "su"
      tramp-default-user "root"
      tramp-default-host "debian")
(add-to-list 'backup-directory-alist (cons tramp-file-name-regexp nil))

It's an environment problem. Tramp sets LC_ALL to "C". You should do the
following, before connecting via "su":

(add-to-list 'tramp-remote-process-environment "LANG=zh_CN.utf8" 'append)
(add-to-list 'tramp-remote-process-environment "LC_ALL=zh_CN.utf8" 'append)

Best regards, Michael.

Yes! It works.
This problem is my headache for a long time. Finally, it's solved.

Thanks, Michael! Thanks you all!
