The reason why I'm asking is because the notation

  \u'HHHH' or \u'HHHHHH'

strikes me as:

1) verbose

2) potentially problematic because of the use of the single quote (which 
might require extra escaping in some contexts)

Best regards, Julian

PS: and, as a nit, it's strange that the syntax uses delimiters but 
doesn't allow sequences of 1 to 3 HEXDIGs...
