It just took me over one hour to find out the unthinkable.
foreach(c; str) will deduce c to immutable(char) and doesn't care about
unicode.
Now there is so many unicode transcoding happening in the language that
it starts to get annoying,
but the most basic string iteration doesn't support it by default?
D has got itself into a tricky situation in this regard. Doing it either
way introduces an unintuitive mess.
The way it is now, you get the problem that you just described where
foreach is unaware of Unicode.
If you changed it to loop as Unicode, then indices won't match up:
immutable(int)[] a = ...
foreach (x, i; a)
assert(x == a[i]); // ok
immutable(char)[] b = ...
foreach (x, i; b)
assert(x == b[i]); // not necessarily!
The index could skip certain indexes to make that assert pass. But that
would be confusing as well.
