Is that even a legal definition? U+005E (^) is, as was mentioned 

earlier in this thread, syntax in LaTeX, so you can't inputenc map it 

to something. Or are you thinking about some attempt at supporting 

verbatim input?

Actually, U+200C (ZERO WIDTH NON-JOINER) seems to me a perfect match to 

\textcompwordmark, and I've entered it as such in my "Draft 

specification for the T1 encoding".



More pragmatically, one may of course write "deaf\-fish" to not only 

escape the ligature, but also point out the proper point of hyphenation.
