I don't even understand why you need the whole table.
You want to not compare some special symbols, and a few other symbols
are equivalent to others. But most symbols are only identical to themselves.
Couldn't you have a much smaller table that only expresses
the exceptions?

They could put some code into their user app that generates
an unique representation.
