  We'll need a way to use possibly different encodings for:

  * File name
  * clipboard
  * keyboard input
  and possibly
  * default system encoding

  Assigning 1006 through 1008 would be good.

I like the symbolic name idea, and vm attribute sounds good to me.

  Thank you for the proposal.  I once signed up to implement it, but
didn't quite get my hands on it.
