Why  not?   That  file  really illustrates  the  international  script
functionality.

That's  a  problem with  encoding,  not  Emacs's international  script
functionality.  Maybe,  you have "conformance to  Unicode and national
encodings" in mind when you said "international script functionality".
They're different issues.

C-x RET c utf-8 C-x s ... does save my Chinese text files in UTF-8.
C-x RET c big5 C-x s ... does save my Chinese text files in BIG5 --
the "native" encoding for traditional Chinese.

And needless to say, I can read  files in UTF-8 and big5 using C-x RET
c ... C-x  C-f.  (For Emacs 20, I need to  install an external package
for Unicode encodings: MuleUCS or something like that.)

Since no  "native" encoding preserves the details  that the emacs-mule
encoding saves, that "showoff" file  must be kept in emacs-mule.  e.g.
the  section "Difference  among chinese  characters in  GB,  JIS, KSC,
BIG5" would  be impossible with Unicode,  GB, JIS, KSC  or BIG5.  Only
emacs-mule have enough coding  space to accomodate all characters from
these  encodings   and  yet   not  unify  them   to  make   them  look
non-identical.
