Maybe it is so.
We have 3 methods to slice UTF-8:
string substr = str[str.toUTFindex(from) .. str.toUTFindex(to)]
//UTF index, not UCS like Sean Kelly wrote
or
string substr = toUTF8(array(takeExactly(drop(str, from), to -
firstIndex)));
or
string substr = toUTF8(toUTF32(str)[from..to]);
But anyway the documentation must be more obvious in this part. I have
learn documentation of D language for 3 days, but I don't understand what
means UTF-8 support from this..
Now I can't to understand how to difference methods which works with
strings at UTF-8 symbols level, and methods which works at bytes level.
The fact which the next code
----
writeln( arr.length );
arr.popFront();
writeln( arr.length );
----
prints 9 after 10 for any array but for UTF-8 and UTF-16 strings may print
as well 8 or lesser, seems too confusing for me.

I agree. The special syntax is unnecessary.
I usually used Japanese, but slice of the UTF-8 string has not become
the problem.
When it is necessary that it looks like it, it is effective to use
dstring(UTF-32).
When I slice it in UTF-8 including the multi-byte character string,
the delimiter is an ASCII code in most cases.
Otherwise, I think that I do not need the special syntax because it is
considerably special processing. (e.g. Regex)

I need to do this from time to time, but I generally just do something
like:
buf[0 .. buf.toUCSindex(n)]
A shorthand might be nice though, I suppose.
Somewhat surprisingly, such a function is rarely needed (I've never
needed
it in working with UTF8)
and so I don't think a special syntax for it is justified.
