	wstring s = toUTF16!string("abc");

Compilation output:
/d500/f513.d(3): Deprecation: function std.utf.toUTF16 is deprecated - To be removed November 2017. Please use std.utf.encode instead.
/d500/f513.d(3): Deprecation: function std.utf.toUTF16 is deprecated - To be removed November 2017. Please use std.utf.encode instead.

You should open an issue on https://issues.dlang.org/

until it is fixed you can use lazy variation byChar, byWchar or byUTF:

void main()
{

        import std.utf : byWchar;
        import std.array : array;

        wstring s = byWchar("abc").array;
}

Help me out, what is the problem with the message?

-Steve

It should not be print? AIAIK std.utf.toUTF16 is not deprecated: http://dlang.org/phobos/std_utf.html#toUTF16

OK this one is:https://github.com/dlang/phobos/blob/v2.075.1/std/utf.d#L2760 (but this one is not in doc)

but this one should not be deprecated: https://github.com/dlang/phobos/blob/v2.075.1/std/utf.d#L2777

Hm.. that's a bug in the compiler. Only one is marked, but both are treated as deprecated.

I'm wondering if just resolving the overload triggers the message.

Please file an issue.

I ran into this too the other day, and found that the issue was already filed:
