<h2>Johnson &amp; Johnson,  $ _  ### ^ ~</h2>

<h3>Description</h3>

<p>This is the description

<td>
<p>space, the item 2</p>
</td></tr>
<tr><td><code id="bah">bah</code></td>

<h3>Details</h3>

<p><span class="rlang"><b>R</b></span> <span class="rlang"><b>R</b></span> \R <code class="reqn">\alpha\beta\Gamma</code>
</p>
<p>In code, all that needs to be escaped is percent, backslash and unpaired
braces: <code>% \ {</code>. Unescaped: <code>$ # _ ^ ~ &lt; &gt; |</code>, and as a
pair, <code>{...}</code>.  If we escape: <code> \_ \# \$ \&amp; { } \ </code>
And some backslashes: <code>\ \ \\ \\</code> should
give one, one, two, two backslashes.
</p>
<p>How about \ (that is backslash space) in text?
</p>
<p>Elsewhere, { } % \ need to be escaped, but not $ # _ ^ ~ &lt; &gt; | .
Let's try that again in <code>\samp</code>: &lsquo;<span class="samp">&#8288; { } % \ $ # _ ^ ~ &lt; &gt; |&#8288;</span>&rsquo;.
And if we do escape: \$ \# \_ , and with three backslashes, \\#.
</p>
<p style="text-align: center;"><code class="reqn">a &lt; b &gt; c | d, x^y</code>
</p>

<p style="text-align: center;"><code class="reqn">\$k &gt; \#k, x_y, x\_y</code>
