[issue27364] Deprecate invalid unicode escape sequences

[R. David Murray]

R. David Murray added the comment:

Yes, this change is likely to break a lot of code, so an extended deprecation period (certainly longer than 3.7, which Guido has already mandated) is the minimum).  Guido hasn't agreed to making it an error yet, as far as I can see ;)
