Nope, that's a radically different matter. As the examples show, the

They're simply not possible. Won't compile.
They do compile.
There is no single UTF-8
code unit for 'ö', so you can't (easily) search for it in a range for
code units.
Of course you can. Can you search for an int in a short[]? Oh yes you
can. Can you search for a dchar in a char[]? Of course you can.
Autodecoding also gives it meaning.
Just like there is no single code point for 'a⃗' so you can't
search for it in a range of code points.
Of course you can.
You can still search for 'a', and 'o', and the rest of ASCII in a range
of code units.
You can search for a dchar in a char[] because you can compare an
individual dchar with either another dchar (correct, autodecoding) or
with a char (incorrect, no autodecoding).
As I said: this thread produces an unpleasant amount of arguments in
favor of autodecoding. Even I don't like that :o).
