Test case and expected output for Safari

The zero-width joiner (ZWJ) does not join glyphs properly in the complex font
path.  (It is ignored in the simple font path: see <a
href="https://bugs.webkit.org/show_bug.cgi?id=16131">bug 16131</a>.)

Safari (4.0.5, 5531.22.7) does not do the shaping at all.  Chromium on Linux
does the shaping correctly, but incorrectly displays the ZWJ glyph between the
joined characters.
