This is the signature of a function of std.ascii:

If this function is supposed to be used on ASCII strings,
what's the point of returning a dchar? When I use it I have
usually to cast its result back to char, and I prefer to avoid
casts in my code in D.

It's not, it only *operates* on ASCII, but non ascii is still a
legal arg:
----
import std.stdio;
import std.ascii;
void main(){
string s = "héllö";
write("\"");
foreach(c; s)
write(c.toUpper);
write("\"");
}
----
HéLLö
