Explicitly mark helper methods that only operate on ASCII ranges

A number of our character helper methods take in wide character types,
but only do tests/operations on the ASCII range of characters. As a
very quick first pass I am renaming all of the foot-gun methods to
explictly call out this behaviour, while I do a bigger
cleanup/refactor.
