f the following is identical:&lt;/p&gt;

&lt;div class="test"&gt;
  &lt;p&gt;&lt;span class="tcy"&gt;123&lt;/span&gt;&lt;/p&gt;
  &lt;p&gt;x&lt;/p&gt;
&lt;/div&gt;</code></pre>
<p>In conforming user agent with the font installed on the system, the span "123" will be combined horizontally thus rendered as a single square, resulting to match the reference. In non-conforming user agents the span will neither be combined nor be compressed as a single square, it will thus not match the reference rendering.
