Autodecode - I've suffered under that, too. The solution was

import std.uni : byCodePoint, byGrapheme;
import std.utf : byCodeUnit;
void main() {

Welcome to my world!

The dstring is only ok because the 2 code units fit in a dchar
right? But all the other ones are as expected right?
Seriously... why is it not graphemes by default for correctness
whyyyyyyy!
