Using a width specifier in conjunction with a utf string fails.  It would be
nice to have a %S modifier that handles this situation.

123456789012345
   Gr��e: incorrect
     Gr��e: correct
Gr��e   : incorrect
Gr��e     : correct
Gr�      : incorrect
Gr��      : correct


import std.stdio;
import std.string;
import std.utf : count;

void
main (string[] args)
{
  string t = "Gr��e";
  size_t width = 10;
  auto len = t.length;
  auto utflen = std.utf.count (t);
  auto tlen = width + len - utflen;
  writefln ("123456789012345");
  writefln ("%10s: incorrect", t);
  writefln ("%*s: correct", tlen, t);
  writefln ("%-10s: incorrect", t);
  writefln ("%-*s: correct", tlen, t);
  writefln ("%-10.4s: incorrect", t);
  auto fmt = format ("%%-%d.%ds: correct", tlen, tlen - 6);
  writefln (fmt, t);
}
