Something like that would be very helpful to sanity check this case.

Uncommon configurations aren't necessarily tested for and removing
multibyte support completely isn't something you'd expect people to do
for anything other than very special uses.  Even so, the pre-multibyte
code is a significant set of code in its own right so if we can test it
so much the better.
