Yes.  It doesn't work because I wasn't in Emacs.  I was in vim inside
mutt, composing an email.  I might have been looking at the source file
in less, or searching it with grep, or even manipulating it with sed or

Anytime you want to do something with such a file with such characters
is a pain.  Even inside Emacs, having to type  C-u C-x = just to find
out what a character is is a pain.

Yes.  But that's only after knowing what it is you have to do.  A
typical Emacs user is going to have to start reading man pages, or
searching the web, or posting on help-gnu-emacs.  I'm not even convinced
a typical user knows about C-x =.
