Yes, R6RS requires string-foldcase to fold capital sigma to small sigma not final sigma. And it requires string-downcase to make final sigma. I'm not sure the reasoning but it probably respects CaseFolding.txt. So may question is; should _string-foldcase_ respect CaseFolding.txt or should do the same as string-downcase?
