If anyone can tell me what code should trigger utf-8 mode via auto-
coding-regexp-alist then I can debug the problem myself.

I'm quite knowledgeable in Emacs Lisp, so if it's in the lisp part
then I can surely debug it.

I took a cursory look into mule.el and I saw auto-coding-regexp-alist
is used there, but I haven't seen any apparent mechanism tying that
stuff to file opening (no find-file-hook or something).

Anyone can give me some pointers regarding this?
