Currently The syntax for \xNNNN hexadeciaml escapes is that it ends whenever
reaching a non-hexadecimal char, and if you need your \xNNN escape to be
followed by an hexidecimal char, then you have to seprate the two with "\ "
(and the Lisp printer does that automatically, of course).
Is there a strong reason not do use the same rule for \u ?
