The original bug isn't windows specific. I don't know if the example from Lucia
Cojocaru can be considered the same bug...

Is this a Windows specific bug?

I tested the following on Linux 64:
  1 import std.conv;
  2 import std.stdio;
  3 import std.utf;
  4 
  5 void main()
  6 {
  7 auto x = to!string(cast(char)191);
  8 auto z = toUTF8(x);
  9 writeln(x);
 10 
 11 
 12 foreach (y; 0 .. 16)
 13 foreach (r; 0 .. 16)
 14 {
 15 auto buffer = to!string(cast(char)(16 * r + y));
 16 auto b = toUTF8(buffer);
 17 writeln(b);
 18 //auto result = buffer.toUTF16z;  // call to utf16z for the
winapi
 19 }
 20 }


Only the commented line throws:
core.exception.UnicodeException@src/rt/util/utf.d(292): invalid UTF-8 sequence

Well since it doesn't throw we may as well make it nothrow :o) and use the
replacement char, or add an overload. I'll bootcamp this.

-
import std.conv;
import std.stdio;

void main()
{
auto x = to!string(cast(char)255);
writeln(x);
}
-

Outputs:
[Decode error - output not utf-8]

I think the to!() routines should be UTF safe so the call to to!string above
should throw an exception. Is this right Andrei?
