That's not true. foreach will only decode on demand:
foreach(c; s) { /* c is a char here, it goes over bytes */ }
Thanks for the correction! Surprised I got foreach(c, s) wrong,
its non-decoding iteration is even the prominent example in TDPL.
Even `each`, the template function that implements a foreach,
still infers as char:
"aä".each!writeln; // prints a plus two broken characters
Only `map`
When I wrote "D's ranges", I meant Phobos's range-producing
templates; a range itself is again encoding-agnostic.
