What do you mean by "existing scheme"? What significant compiler
(i.e. one selling more than 10000 copies per year) implemented
them? They seem to be probably the worst misfeature of ANSI C:
one that actually breaks working code. I have some code,
based on K&R C that uses the sequences ??(, ??), and ??! as
delimiters in a text file format - they are used in jillions
of string constants. Wouldn't trigraphs break such schemes?
