<p>Name tests are performed on QNames in XML document instead of expanded names; for <code>&lt;foo xmlns:ns1='uri' xmlns:ns2='uri'&gt;&lt;ns1:child/&gt;&lt;ns2:child/&gt;&lt;/foo&gt;</code>, query <code>foo/ns1:*</code> will return only the first child, not both of them. Compliant XPath implementations can return both nodes if the user provides appropriate namespace declarations.</p>
</li>
<li>
<p>String functions consider a character to be either a single <code>char</code> value or a single <code>wchar_t</code> value, depending on the library configuration; this means that some string functions are not fully Unicode-aware. This affects <code>substring()</code>, <code>string-length()</code> and <code>translate()</code> functions.</p>

<ul>
<li>
<p>Major Unicode improvements:</p>
<div class="olist arabic">
<ol class="arabic">
<li>
<p>Introduced encoding support (automatic/manual encoding detection on load, manual encoding selection on save, conversion from/to UTF8, UTF16 LE/BE, UTF32 LE/BE)</p>
</li>
<li>
<p>Introduced <code>wchar_t</code> mode (you can set <code>PUGIXML_WCHAR_MODE</code> define to switch pugixml internal encoding from UTF8 to <code>wchar_t</code>; all functions are switched to their Unicode variants)</p>
</li>
<li>
<p>Load/save functions now support wide streams</p>

</li>
<li>
<p>XPath string/number conversion improvements (increased precision, fixed crash for huge numbers)</p>

<div class="olist arabic">
<ol class="arabic">

<p>Performance improvements:</p>
<div class="olist arabic">
<ol class="arabic">
<li>
<p>Optimized document parsing and saving</p>

<p>Compatibility:</p>

</li>
<li>
<p>Fixed axis tests: they never add empty nodes/attributes to the resulting node set now</p>
</li>
<li>
<p>Fixed string-value evaluation for node-set (the result excluded some text descendants)</p>
</li>
<li>
<p>Fixed <code>self::</code> axis (it behaved like <code>ancestor-or-self::</code>)</p>
</li>
<li>
<p>Fixed <code>following::</code> and <code>preceding::</code> axes (they included descendent and ancestor nodes, respectively)</p>
