Before I switched completely to "nodelist based typesetting" I used a special catcode table. As I am no TeX expert at all (I always fight with catcodes), there are probably mistakes or room for improvement in the following code:

\catcode`\^= 12
\catcode`\$= 12
\catcode`\_= 12

This made all characters harmless except for ¬, the new escape character. So, this is an example, but don't take this as "the way to go".
