You are on GNU/Linux, right?  Because the above will not work on
Windows, because UTF-8 os not reliably supported, not even in Windows
10 (which added some improvements in that area).

But perhaps this could help:

  (set-language-environment "Chinese-Big5")

However, it's possible that even this will not help, unless the system
codepage is changed to something that can support Chinese.
