Even though that's possible, why add more magic to the codec registry ?
u.encode('latin-1', 'xmlcharrefreplace') looks much clearer to me.
You are of course free to write a codec which implements this
directly. No change to the core is needed for that.
However, PEP 293 addresses a much wider application space than
just escaping unmappable characters.
