<h2>Detailed Description</h2>
<p>The QTextDecoder class provides a state-based decoder.</p>
<p>A text decoder converts text from an encoded text format into Unicode using a specific codec.</p>
<p>The decoder converts text in this format into Unicode, remembering any state that is required between calls.</p>

<p>Constructs a text decoder for the given <i>codec</i> and conversion <i>flags</i>.</p>
<p>This function was introduced in Qt 4.7.</p>
<!-- @@@QTextDecoder -->
<!-- $$$~QTextDecoder[overload1]$$$~QTextDecoder -->
<h3 class="fn"><a name="dtor.QTextDecoder"></a>QTextDecoder::<span class="name">~QTextDecoder</span> ()</h3>
<p>Destroys the decoder.</p>

<p>Converts the first <i>len</i> bytes in <i>chars</i> to Unicode, returning the result.</p>
<p>If not all characters are used (e.g&#x2e; if only part of a multi-byte encoding is at the end of the characters), the decoder remembers enough state to continue with the next call to this function.</p>
