<p>Returns a <a href="qstring.html">QString</a> initialized with the first <i>size</i> characters from the string <i>str</i>.</p>
<p>If <i>size</i> is -1 (default), it is taken to be strlen(<i>str</i>).</p>
<p>This function does the same as <a href="qstring.html#fromLatin1">fromLatin1</a>().</p>
<p><b>See also </b><a href="qstring-obsolete.html#toAscii">toAscii</a>(), <a href="qstring.html#fromLatin1">fromLatin1</a>(), <a href="qstring.html#fromUtf8">fromUtf8</a>(), and <a href="qstring.html#fromLocal8Bit">fromLocal8Bit</a>().</p>

<p>This is an overloaded function.</p>
<p>Returns a <a href="qstring.html">QString</a> initialized with the string <i>str</i>.</p>
<p>This function was introduced in Qt 5.0.</p>

<!-- @@@sprintf -->
<!-- $$$toAscii[overload1]$$$toAscii -->
<h3 class="fn" id="toAscii"><a name="toAscii"></a><span class="type"><a href="qbytearray.html">QByteArray</a></span> QString::<span class="name">toAscii</span>() const</h3>
<p>Returns an 8-bit representation of the string as a <a href="qbytearray.html">QByteArray</a>.</p>
<p>This function does the same as <a href="qstring.html#toLatin1">toLatin1</a>().</p>
<p>Note that, despite the name, this function does not necessarily return an US-ASCII (ANSI X3.4-1986) string and its result may not be US-ASCII compatible.</p>
