I've just started using wave, but it occurs to me that there are some 
basic things I don't understand about it, and which aren't (I think) 
covered in the online docs. Does anyone know:

1 - presumably wave uses UTF-8? Will it accept arbitrary UTF-8 files? 
What if the source starts with a 3-byte UTF-8 BOM?

2 - how closely does the source have to conform to C/C++ code? I can 
understand that the source has to follow basic lexing conventions (use 
of apostrophes, and so on), but wave actually seems to carry out full 
C++ lexing. Why is this necessary - could it just process 
whitespace-delimited tokens (outside comments)? The reason I'm asking is 
that I'm pre-processing arbitrary non-C code. This seems to be Ok if I 
disable whitespace insertion for disambiguation, but I'd just like to be 
sure that I'm not missing something.

Thanks -

Paul
