Ok, here's how I can see this being done:
1. define a new field for the buffer object which is a char-table.
2. Populate this table in lisp code.
3. Use it instead of the case folding table as the translation table for se= arches, if some given variable is non-nil.

Would that be desirable?

We could also use the equivalence class folding table in add= ition to the case folding table. But that would (in the very least) involve= changing the c search functions to take an additional argument.

Just a warning: the case-tables are threatened.=C2=A0 They should be replac= ed by
Unicode-aware (locale-dependent?) case folding for the 99.99% of the
cases, the only remaining case is the "ASCII upcase/downcase" ope= ration
used in sendmail.el (IIRC), which we can hopefully solve some other way.
