<h3><a class="toc-backref" href="#id2">Initializing the Class</a><a class="headerlink" href="#initializing-the-class" title="Permalink to this headline">¶</a></h3>
<p>Like most other classes in CodeIgniter, the Typography class is
initialized in your controller using the <tt class="docutils literal"><span class="pre">$this->load->library()</span></tt> method:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$this</span><span class="o">-></span><span class="na">load</span><span class="o">-></span><span class="na">library</span><span class="p">(</span><span class="s1">'typography'</span><span class="p">);</span>
</pre></div>
</div>
<p>Once loaded, the Typography library object will be available using:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$this</span><span class="o">-></span><span class="na">typography</span>
</pre></div>
</div>
</div>

<dd><dl class="attribute">
<dt>
<tt class="descname">$protect_braced_quotes = FALSE</tt></dt>
<dd><p>When using the Typography library in conjunction with the <a class="reference internal" href="parser.html"><em>Template Parser library</em></a>
it can often be desirable to protect single and double quotes within curly braces.
To enable this, set the <tt class="docutils literal"><span class="pre">protect_braced_quotes</span></tt> class property to TRUE.</p>
<p>Usage example:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$this</span><span class="o">-></span><span class="na">load</span><span class="o">-></span><span class="na">library</span><span class="p">(</span><span class="s1">'typography'</span><span class="p">);</span>
<span class="nv">$this</span><span class="o">-></span><span class="na">typography</span><span class="o">-></span><span class="na">protect_braced_quotes</span> <span class="o">=</span> <span class="k">TRUE</span><span class="p">;</span>

<p>This method is similar to <tt class="docutils literal"><span class="pre">auto_typography()</span></tt> above, except that it only does character conversion:</p>
<blockquote>
<div><ul class="simple">
<li>Quotes are converted to correctly facing curly quote entities, except those that appear within tags.</li>
<li>Apostrophes are converted to curly apostrophe entities.</li>
<li>Double dashes (either like – this or like–this) are converted to em—dashes.</li>
<li>Three consecutive periods either preceding or following a word are converted to ellipsis (…).</li>
<li>Double spaces following sentences are converted to non-breaking spaces to mimic double spacing.</li>
</ul>
</div></blockquote>
<p>Usage example:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$string</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-></span><span class="na">typography</span><span class="o">-></span><span class="na">format_characters</span><span class="p">(</span><span class="nv">$string</span><span class="p">);</span>

<p>Converts newlines to <br /> tags unless they appear within <pre> tags.
This method is identical to the native PHP <tt class="xref php php-func docutils literal"><span class="pre">nl2br()</span></tt> function, except that it ignores <pre> tags.</p>
<p>Usage example:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$string</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-></span><span class="na">typography</span><span class="o">-></span><span class="na">nl2br_except_pre</span><span class="p">(</span><span class="nv">$string</span><span class="p">);</span>
