That kind of violate OWTDI though. Probably one's enough.

and if fact with the use-cases I can think of, and the one you mentioned,
they are really two steps: there are the characters you want to translate,
and the ones you want to keep, but the ones you want to keep are a superset
of the ones you want to translate. so if we added the "remove"option to
.translate(), then you would need to add all the "keep" charactors to your
translate table.

I'm thinking they really are different operations, give them a different
method.
