This feature still awaits a volunteer to be added to Emacs. It
shouldn't be too hard, I think.

The customization I suggested, i.e.
(prefer-coding-system 'euc-jp)
was supposed to make euc-jp of higher priority than GBK (and
everything else). However, I understand it did you more harm than
good.
For more fine-grain control, try calling set-coding-system-priority
for every encoding you need to deal with, and in such an order that
the resulting list returned by coding-system-priority-list would show
the encodings in the order you want them. (These two functions are
documented in the ELisp manual.) I'm not sure this will have the same
effect as ":set fencs" in vim, though.

I would try to find a program that could print a file's
encoding. `file' does not do that, but maybe there's something else
out there.
