Section A.3 says:
EmbeddedUnicodeChar = %x5C.7A 4HEXDIG ; starts with "\u"
It should say:
EmbeddedUnicodeChar = %x5C.75 4HEXDIG ; starts with "\u"
Hex 7A is the character 'z', which doesn't match the comment.
As far as I can tell, the Java language defines unicode characters to be \u, like the comment says, and therefore the ABNF should be %x5C.75
