Let's take a new character, say DEL ('\177'). We could define that for
UTF-8 terminals, DEL always erases the last character, i.e. - for the
nonproportional case - corresponds to a number of "\b \b" sequences.

This would have the benefits of
  1. avoiding incompatibilities caused by disagreeing wcwidth definitions,
  2. making terminals with nonproportional fonts better supported,
  3. being a feature not provided in traditional CJK environments.

Which is the standards body where we could submit such a proposal?
