Just noticed that the spec only supports four hex digits; this would
imply that support for anything outside the BMP would have to be done
by encoding the character as a surrogate pair. If the code doesn't
do this already (the original patch didn't seem to) these should be
normalised back to a single character in a similar manner to Marko's
recent patch[1].

OK, sounds reasonable.
