Agreed; normalizing the source should be applied only to code points;
the code sequence <0x5c, 0x75> normalizes to itself.  If there is a \u
in a string, it will still be there after normalization, before python
lexes.  If there is a \u outside a string, it will still be there to
cause syntax errors.
