I used vi regexps directly, and recorded those in the C source file :-) !
:1,$ s/\[#x\([0-9A-Z]*\)-#x\([0-9A-Z]*\)\]/ (((c) >= 0x\1) \&\& ((c) <= 0x\2)) ||/
and
:1,$ s/#x\([0-9A-Z]*\)/ ((c) == 0x\1) ||/
of course the result was later modified a bit to speed up the test.
In order to try to turn a useless post into an useful one, did someone
tried to implement the character normalization checking of XML-1.1 ?

I looked at the ICU sample code a few months ago and this simply scared
me mostly due to my perception of that code complexity and runtime cost.
