A general toupper/tolower for Unicode is doomed to fail. As 
already mentioned Turkish has its specificity, but other 
languages also have traps. In Greek toupper/tolower are not 
reversible i.e. `x.toupper.tolower == x` is not guaranteed . Some 
languages have 1 codepoint input and 2 codepoints as result 
(German ß becomes SS in most cases, capital ẞ is not the right 
choice in most cases).
etc. etc.
