How convert String to Fixed wchar Array?
import std;

string name = "Marvin";
wchar[255] wtext = name.to!(wchar[]); // Can not convert.
writeln(wtext);

void main()
{
string name = "Marvin";
wchar[255] wtext;
import std.range;
wchar[] buf = wtext[];
put(buf, name);
auto setLen = wtext.length - buf.length; // number of wchars set in
wtext.
writeln(wtext[0 .. setLen]);
}
A little bit of explanation: wchar[] is an output range that can accept
any form of text. When you use `put` on it, it writes to it, AND shrinks
from the front to allow remembering where it was. So at the end, buf is
pointing at what is *left* in the buffer.
There may be better ways to do this, but this way will avoid any extra
GC allocation.
