Boolean (positional?) parameters? Ick. Make them named parameters, 
and/or introduce new functions into the namespace, such as casefold_TR() 
[would people confuse ISO .tr with tr///?] and
casefold_variable_length() [but that's too verbose].

Lock the implementations down into separate API functions (even if they 
call an underlying workhorse function). A multi-modal function helps no-one.
