Well, of course it depends on the settings of your language
environment.  utf-8 can't be detected reliably in all circumstances.
C-x RET f does not change the interpretations of the characters in
your buffer, but with what encodings they will get saved again.

You have to specify the coding system already when loading the file,
like with

C-x RET c utf-8 RET C-x C-f crap.reg RET

If you already loaded the file, you need to reload:

C-x RET c utf-8 RET C-x C-v RET
