So basically the above just doesn't work. Prints gibberish.
Because you're printing one UTF-8 code unit (`char`) per line.
So I figured, std.uni.byGrapheme would help, since that's
what they are, but I can't get it to print them back out? Is
there a way?
foreach (c; "👩👩👦👦🏳️🌈".byGrapheme) {
writeln(c.<????>);
}
You're looking for `c[]`. But that won't work, because std.uni
apparently doesn't recognize those as grapheme clusters. The
emojis may be too new. std.uni is based on Unicode version
6.2, which is a couple years old.
Oops! I didn't realize this, ignore my message about reporting
a bug.
I still think it's very odd for printing a grapheme to print
the data structure.

Aha, ok I see. Many gracias!
Though, seems by a couple years old you mean 6 years! :) Is
updating unicode stuff to the latest a matter of some config file
somewhere with the code point configurations that result in
specific graphemes? Feels kinda ... quite bad that we're 6 years
behind the current standard.
Also, any reason (technical or otherwise) that we have to slice a
grapheme to get it printed? Or just no one implemented something
like toString or the like? It's quite non intuitive as it is
right now IMO. I can't really imagine anyone figuring out that
they have to slice a grapheme to get it to print 🤔
