My understanding was that the Turkish,... I/i was one of the main cases
that led to the separation of input mappings such as case foldings from
the protocol itself, to allow these input mappings to depend on locale.
I.e. a Turkish,... system would map 'I' to lowercase i without dot,
whereas on other systems, it would map simply to 'i'. If we can't get
that to work somehow, then I don't see the point of locale-dependency.
