1. They have case-insensitive versions of pretty much

It's not hard to do a map!toLower/toUpper in D but it's also
not
obvious (nor do I know if that's actually correct in languages
outside of english).
Uppercase, lowercase, and case-insensitive comparison is
locale-dependent for Unicode. In the general case you can't
just compare the lowercase/uppercase versions. For instance,
look at the Turkish i/İ and ı/I (dot-less i), or the German
ß/SS ss/SS pairs. Also, if you're sorting in alphabetical order
you probably want to do something special with diacritics.
The correct way to to this is to implement the Unicode
Collation Algorithm:

I thought it was probably more complicated than that.
Looks like Dmitry put it in the tracker:
