Hello:

Before I use:

 ;; Local Variables:
 ;; coding: utf-8-unix
 ;; End:

Can I change it to the below?

 ;; Local Variables:
 ;; coding: utf-8-emacs-unix
 ;; End:


If I just save Chinese?

utf-8-emacs is the coding system used by Emacs to internally represent
multibyte values, which includes non-Unicode characters.

I don't think it's ever a good idea to save files for human consumption
in that encoding, but both coding systems should encode ordinary Chinese
text the same way.

There's a description about utf-8-emacs from Emacs info manual, under
section Coding Systems:

The internal encoding is a "superset" of unicode, so at least you can
expect it is compatible with the utf-8-unix.
