'fileencodings' should also be set, but perhaps it's already OK because
of other rules in the option initialization. Needs to be checked.

So basically you want to set 'encoding' to "cp936", but not use the
alias. So that most files can be edited without trouble, and conversion
still works for people who need the extra characters. Thus instead of
falling back to "utf-8" in set_init_1() you would fall back to "cp936".
Then no other options need to be set (hopefully).
Try this patch:
