For use with another program which generates C++ as output, I made an
encoding scheme ("mangling") that translates an arbitrary string into a
C/C++ identifier. For header macro names, I prepend "header_".

This is convenient for use with automated outputs.

Great. Why not writing out the undefined characters (range 1..255) as well,
and changing "$undefined." to something more aesthetical as well.
