std.uni.Grapheme is a struct, and that struct contains a string of arbitrary length.

I don't know if that is the right design or not, or if a Grapheme should instead 
be an alias for a slice (rather than be a distinct type).

Graphemes do not appear to have a 1:1 mapping with dchars, and any attempt to do 
so would likely be a giant mistake.
