I know that these aren't used much at the moment, but section 3.2 of the ADL draft is wrong because it suggests that
\uHHHH \uHHHHHHHH are both acceptable quotation forms for unicode character points. However, I think that the long form (HHHHHHHH) must have a capital U to distinguish it. It is not possible to distinguish the forms based on the number of H characters because the H characters could legitimately be part of the actual string. For instance, to express 1000 euros I might use \u20AC1000 which would be interpreted as an 8 digit unicode point rather than ?1000 Andrew
