In D, we can write code that is both Unicode-correct and highly performant,

a modicum of understanding of how Unicode works (in order to choose the right
tools from the toolbox), but I think it's a novel compromise.
Sadly, std.array is determined to decode (i.e. convert to dchar[]) all your
strings when they are used as ranges. This means that all algorithms on strings
will be crippled as far as performance goes.

Very, very few operations on strings need decoding. The decoding should have
gone into a separate layer.
