what's the correct way to handle unicode? - trying to print out graphemes here.

Hi, trying to figure out how to loop through a string of 
characters and then spit them back out.

Eg:

foreach (c; "👩‍👩‍👦‍👦🏳️‍🌈") {
   writeln(c);
}

So basically the above just doesn't work. Prints gibberish.

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.<????>);
}

And then if I type the loop variable as dchar,  then it seems  
that the family empji is printed out as 4 faces - so the code 
points I guess - and the rainbow flag is other stuff (also its 
code points I assume)

Is there a type that I can use to store graphemes and then output 
them as a grapheme as well? Or do I have to use like lib ICU 
maybe or something similar?

Cheers,
