Remove UTF-8 characters from comments

I've used an operating system for over 10 years now that makes
UTF-8 easy. It's not called Linux or OSX.

When UTF-8 is needed, of course, then we can look again.
I can't think of a single redeeming feature of placing
it in the comment in this manner. It's certainy not
needed.

The inclusion of UTF-8 characters is inconvenient,
especially from a text terminal.
I don't really want to start using compose in
CROSH shell terminals on chromeos.

We might want to incorporate "no UTF-8" as a
commit filter. For now, get rid of these
characters.
