*A windows API functions are for ASCII only.
You need the *W varients which are unicode.
For this you could use std.conv : to.

wstring text = "my str".to!wstring;

Or at least I'm pretty sure that will work for you.

The second one is correct yes.
I'm just assuming that it isn't compiled into the executable.

Either is fine.  Non-suffixed string literals have a default type of 
string, but implicitly convert to wstring/dstring at compile time.

MessageBoxA <- A is ANSI.

You should try with MessageBoxW, for unicode I guess.

You can also try using a wide string literal, i.e. "你好，世界"w. The 
suffix forces the string to use 16-bit characters.

The garbled display from writeln might be related to your console 
settings. If you aren't using the UTF-8 codepage in cmd.exe, that 
would explain why the text appears garbled. Unfortunately, 
Windows has some significant bugs with UTF-8 in the console.

 Windows has some significant bugs with UTF-8 in the console.

This is really our problem. We pretend the output terminal is
UTF-8 without providing any means to configure the terminal or
converting the output to the terminal's encoding. All OSs
provide conversion API that works for the most part (assuming
normalization form D for example), but we just don't use them.
Most contributers were on Linux or English Windows system
where the issue is not obvious. But even in Europe =C5=82=C3=A1=C3=B6 will
come out garbled.

Now this is mostly not an issue with modern Linux and OS X as
the default is UTF-8, but some people refuse to change to
variable length encodings and Windows has always been
preferring fixed length encodings.

The proper way to solve this for the OP in a cross-platform
way is to replace writeln with something that detects whether
the output is a terminal and then converts the string to
something that will display correctly, which can be a simple
wchar[] on Windows or the use of iconv on Linux. Ketmar is
currently using iconv to print D string on his Linux set up
for Cyrillic KIO-8U and I think I used it in some code as
well. It is not perfect, but will make most printable strings
readable. ICU I think is the only library that gets it 100%
correct with regards to normalization and offering you
different error concealment methods.

I solved it.
windows console like:

setlocale(0, cast(char*)"china");
auto str = "你好，世界";
writeln(str);

MessageBox like:
const wchar *wstring = toUTF16z("你好，世界");
MessageBoxW(null,wstring,wstring,0);

You shouldn't need this cast. Try removing it; if it doesn't 
compile, something's wrong.

 auto str = "你好，世界";
 writeln(str);

 MessageBox like:
 const wchar *wstring = toUTF16z("你好，世界");
 MessageBoxW(null,wstring,wstring,0);

No, I'm talking specifically about the cast in there, not the 
call to setlocale(). Does it still work if you replace this:

     setlocale(0, cast(char*)"china");

by that:

     setlocale(0, "china");

?
