Actually, for ASCII characters, it uses 8 bits. For any unicode
character that needs more than that, a code is used to initiate an
extended sequence (in this case, the a-circumflex) and other bytes
follow. I believe there are unicode characters that require more than

I know there's a setting in mine. It's the Text Encoding, which might
be set to be ISO Latin. It's usually the default.

If you see MIME separators and the like, the mailer hasn't processed
them. I usually only see this in SPAM.

It's not the keyboard, it's the software. In some text editing
software, and I guess emailers, doing a " after a space will give you
the right quote, and after other characters, the left quote. Same with
the apostrophe. I hated it when Word used to do that to me... Mac Word
Version 5 (long time ago) did it, and I turned it off as soon as I
figured out how.
I had always wondered why ` was used... :) now I know. :)
