I think that I remember to have read about so-called catcodes (or
whatever?) in TeX, which apparently make it possible to declare certain
characters as "active" so that further processing is possible whenever
the TeX scanner reads such character. I wonder if it is possible this way
to declare in the preamble that
"C" followed by "+", followed by "+"
is "active" and should be inherently substituted with something like
"\mbox{C+\hspace{-.5ex}+}}"
Quick shot: [...]
Somewhat improved version:
\def\plus{+}
\catcode`\+=\active
\def\smallplusplus#1{\raisebox{0.6ex}{\tiny\plus\kern-.3ex\plus}}
\def+{\futurelet\nextchar\pluss}
\def\pluss{%
\ifx\nextchar+%
\let\next\smallplusplus%
\else%
\let\next\plus%
\fi%
\next}
And no, I can't explain it.
If you could, I'd be really worried about you. ;-)
