    Test for <i><a href="https://bugs.webkit.org/show_bug.cgi?id=34735">https://bugs.webkit.org/show_bug.cgi?id=34735</a> [Chromium] OpenType font with CFF glyphs is not handled correctly on Windows XP</i>.
</p>
<p>Check if glyphs in Ahem.otf can be rendered correctly. If the test passes, you should see dozens of black square characters below:</p>
<span style="font-family: family1">!"#$%&amp;()*+,-./0123456789:;&lt;=&gt;?@ABCDEFGHIJKLMNO</span>
<span style="font-family: family1">PQRSTUVWXYZ[\]^_`abcdefghijklmnoqrstuvwxyz{|}~</span>
<!-- space, single-quote, and small p are omitted since they are not black squares -->
<p>Check if glyphs not in Ahem.otf can be rendered using a fallback font. If the test passes, you should see a single-quote character below:</p>
<span style="font-family: family1">'</span>
<!-- Ahem font does not have a glyph for ' -->
