[ruby-core:63517] [ruby-trunk - Feature #10002] String swapcase

Issue #10002 has been updated by Shyouhei Urabe. We are talking about swapcase, not folding. The "generally they are not rev= ersible" you say is the difficulty we are facing here. Also as you cited C= aseFolding.txt, you should have been aware of type T folding, which is impo= ssible without locale information. If you think you can implement it, please show us.
