proposed patch

I have a 9 MB file that produces this message a large number of times.
It looks like the file has <00##> where pdftops expects a two-digit value.
The attached patch to CharCodeToUnicode.cc fixes the problem by allowing either
<##> or <00##>.
Several places in CharCodeToUnicode.cc produce the identical error message.  My
patches also make the messages slightly different to help localize the problem.
