7-bit ASCII is completely compatible with UTF8.  UTF8 was designed
with compatibility in mind, so that existing (ASCII) text strings
would automatically "be" UTF8 - i.e. no conversion needed.

I also don't see any reason why they can't simply be 7-bit ASCII,
otherwise known as IRA - the International Reference Alphabet.
Also note that the ISO 8859-x character sets (locales?) are
(as far as I recall) compatible in the first 128 characters
with IRA/ASCII.
