Well, certainly, Unicode have specifications for those corner
cases, so we could say "the symbols are case-folded according
to Unicode standard 4.0's section 5.18" or something. But
do we want any human reader of the Scheme program to know those
case-folding rules? These days it is getting common to see code
that are written by someone from different tongue.
BTW, for the backward compatibility: R6RS will likely to have
some sort of incompatibilities, so implementations who wants
to use legacy code will have some sort of compatibility mode
anyways. I don't think it is difficult for the implementations
to have "R5RS compatibility reader" mode---many implementations
already have such means.
