Becasue Graphemes do not auto-magically convert to dchar and back?
After all
they are just small strings.
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).
They use small-string optimization with great success, as indeed plenty
of graphemes are just 1 codepoint. Many others are just a couple.
Graphemes do not appear to have a 1:1 mapping with dchars, and any
attempt to do so would likely be a giant mistake.
