We use unicode_escape (actually raw_unicode_escape) in the email package,
and there we are converting between string and bytes.  It is used as an
encoder when we are supposed to have ASCII input but have other stuff,
and need ASCII output and don't want to lose information.  So yes,
that encoder does still make sense.  It would also be useful as a
transform function, but as someone has pointed out there's an issue
for that.
