Wrong output of quotes in Windows (encoding?)

Is the code page also set to UTF-8? I think you must issue the command 
'chcp 65001'.

I have changed your program to print the code units individually in hex. 
I changed the test string to a single space character so that you can 
identify it easily on the output:

import std.stdio, std.string, std.encoding;

@trusted string quote(in string str, in char chr = 'd') pure {
   switch(chr) {
     case 'b': return '`' ~ str ~ '`'; // backtick
     case 'd': return `"` ~ str ~ `"`; // double
     case 'f': return `«` ~ str ~ `»`; // french
     case 's': return `'` ~ str ~ `'`; // single
     case 't': return `“` ~ str ~ `”`; // typographic
     default: return `"` ~ str ~ `"`; // double
   }
}

void main() {
   char[] a = ['b', 'd', 'f', 's', 't'];
   auto input = " ";
   foreach(char type; a)
       writeln(format("Quote type %s:\t%(%02x %)", type,
                      cast(ubyte[])quote(input, type)));
}

Does the output of the program look correct according to UTF-8? Then 
your compiler has produced a correct program. :) Here is the output I 
get on SL6.1 compiled with dmd v2.065-devel-41ebb59:

Quote type b:	60 20 60
Quote type d:	22 20 22
Quote type f:	c2 ab 20 c2 bb
Quote type s:	27 20 27
Quote type t:	e2 80 9c 20 e2 80 9d

I trust the correctness of this feature of D so much that I am too lazy 
to check whether those code units correspond to the intended Unicode 
characters. :)
