This is questionable. This would have the consequence that \udcxx in a python 
string would sometimes mean a surrogate, and sometimes mean raw bytes, depending 
on the history of the string.
By contrast, if the new utf-8b codec would *supercede* the old one, \udcxx would 
always mean raw bytes (at least on UCS-4 builds, where surrogates are unused). 
Thus ambiguity could be avoided.
