I don't think char-table expertise will help here. The main issue is
what uses of this data we envision.

No, let's think what uses we envision, and make the data structure
convenient for those uses.

Should it be a list or a string? How would you use this mapping?

The RHS of a mapping can be several characters, in which case there's
no reverse mapping and no "confusables mapped to a character", I think.

What would be a possible use of that?
