\Sorry, but ".)" is already a valid sequence in C code:  x=cos(1.)

My mistake, sorry indeed.

\If you're going to followup with an improved proposal, please note that there
\are nine characters ( #[\]^{|}~ ) to be handled.

The only digraph solutions I can think of, are the use of '$', '`' or '@';
however, isn't it strange that the latter, being such a wierd character,
is supposed to be available on every terminal?
