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> \a \b \_ \# \$ \&amp; { } \ </code>
And some backslashes: <code>\ \ \\ \\</code> should
give zero, one, one, 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>: <span class="samp"> { } % \ $ # _ ^ ~ &lt; &gt; |</span>.
And if we do escape: \$ \# \_ , and with three backslashes, \\#.
