Perhaps the file is detected as raw bytes.

I've just installed the attached fix so that the menu "Set
Coding Systems" is not greyed-out as far as Emacs is in
multibyte mode even if the current buffer is unibyte.

And, the HEAD version has this menu (which is also bound to
C-x RET r):

<menu-bar> <options> <mule> <set-various-coding-system>
<revert-buffer-with-coding-system>

When you select this menu, Emacs asks you to type a coding
system name, and re-visit the buffer file with the specified
coding system.

Isn't it what you want?
