Well, while we cannot map uppercase I to lowercase dotless i...
Is it an absolute necessity to stick with case *folding*?
Why would not toLower (not specialised for Turkish) be viable
for IDN? That would keep/allow both lowercase sharp s and
lowercase dotless i (and even terminal sigma). A domain
name entered in uppercase form might not be ideally mapped to
lowercase, but is that necessarily expected?
