<p>Test is passed if:</p>
<ol>
<li>The word fijord on the first line uses an <strong>fi</strong> ligature</li>
<li>It is clear that the second line has a letter f followed by a Turkish dotless-i while the third line has a letter f followed by a (dotted) i. If an <strong>fi</strong> ligature is used on either the second or third line, it must still be possible to distinguish the two.</p>
