								<p>Glyph doesn&#8217;t require any special control characters like LaTeX, and its macro syntax is very straightforward and liberal. This however comes with a price: because square brackets are used as delimiters, you must escape any square bracket in your text with a backslash. That&#8217;s not <em>too</em> bad if you think about it, unless you&#8217;re writing programming code, in which case escaping every single square bracket can be painful.</p>
<p>If a portion of your text contains an excessive amount of square brackets, you may consider using the <a href="/glyph/book/macros/macros_core.html#m_escape"><code>escape</code></a> macro (or its alias <code>.</code>) with the <code>[=</code> and <code>=]</code> delimiters. By itself, the escape macro doesn&#8217;t do anything: it just evaluates to its contents, but the special delimiters act as an escape for any square bracket within them. As a consequence, any macro within <code>[=</code> and <code>=]</code> will <em>not</em> be evaluated.</p>
<p>You can use the quoting delimiters with <em>any</em> macro identifier. Obviously, using them as delimiters for things like <a href="/glyph/book/macros/macros_structure.html#m_section"><code>section</code></a> macros may not be a good idea, but they should be more or less mandatory with the <a href="/glyph/book/macros/macros_block.html#m_codeblock"><code>codeblock</code></a> macro or the <a href="/glyph/book/macros/macros_filters.html#m_highlight"><code>highlight</code></a> macro, especially when it contains square brackets or even Glyph code, like this:</p>

	<div class="CodeRay">
  <div class="code"><pre><span class="no"> 1</span> codeblock[=
<span class="no"> 2</span>   section[
<span class="no"> 3</span>     @title[A section]
<span class="no"> 4</span>     @id[test]
<span class="no"> 5</span> This is a section.
<span class="no"> 6</span>     section[
<span class="no"> 7</span>     @title[A nested section]
<span class="no"> 8</span> This is another section.
<span class="no"> 9</span>     ]
<span class="no"><strong>10</strong></span>   ]
<span class="no">11</span> =]</pre></div>
</div>


	<aside class="note">
<span class="note-title">Note</span>Although quoting delimiters allow you to use square brackets without escaping them, you must still escape them if you want to escape quoting delimiters themselves.

</aside>

	<p>Besides square brackets, there are other characters that must or can be escaped with backslashes, as shown in the following table:</p>

	<table><tr><th>Escape Sequence</th>
   		<th>Evaluates to...</th>
   		<th>Notes</th></tr>
 		<tr><td>
<code>\[</code>
</td>
   		<td>
<code>[</code>
</td>
   		<td>Square brackets must be escaped unless used as macro delimiters or within a quoting macro.</td></tr>
 		<tr><td>
<code>\]</code>
</td>
   		<td>
<code>]</code>
</td>
   		<td>Square brackets must be escaped unless used as macro delimiters or within a quoting macro.</td></tr>
 		<tr><td>
<code>\\</code>
</td>
   		<td>
<code>\</code>
</td>
   		<td>Backslashes do not have to be escaped by default, but an escaped backslash will evaluate to itself.</td></tr>
 		<tr><td>
<code>\=</code>
</td>
   		<td>
<code>=</code>
</td>
   		<td>Equal signs do not have to be escaped by default, but an escaped equal sign will evaluate to iself.</td></tr>
 		<tr><td>
<code>\|</code>
</td>
   		<td>
<code>|</code>
</td>
   		<td>Pipes must be escaped (even within quoting macros) unless they are used to separate macro parameters.</td></tr>
 		<tr><td>
<code>\.</code>
</td>
   		<td />
   		<td>An escaped dot evaluates to nothing. Useful to separate macro identifiers from other characters: <br /><code>_\.=>[#link|This link is emphasized using Textile]_</code></td></tr></table>
