[#xml_encoding]
pugixml supports all popular Unicode encodings (UTF-8, UTF-16 (big and little endian), UTF-32 (big and little endian); UCS-2 is naturally supported since it's a strict subset of UTF-16) and handles all encoding conversions. Most loading functions accept the optional parameter `encoding`. This is a value of enumeration type `xml_encoding`, that can have the following values:
-* [anchor encoding_auto] means that pugixml will try to guess the encoding based on source XML data. The algorithm is a modified version of the one presented in Appendix F.1 of XML recommendation; it tries to match the first few bytes of input data with the following patterns in strict order:
- * If first four bytes match UTF-32 BOM (Byte Order Mark), encoding is assumed to be UTF-32 with the endianness equal to that of BOM;
- * If first two bytes match UTF-16 BOM, encoding is assumed to be UTF-16 with the endianness equal to that of BOM;
- * If first three bytes match UTF-8 BOM, encoding is assumed to be UTF-8;
- * If first four bytes match UTF-32 representation of [^<], encoding is assumed to be UTF-32 with the corresponding endianness;
- * If first four bytes match UTF-16 representation of [^<?], encoding is assumed to be UTF-16 with the corresponding endianness;
- * If first two bytes match UTF-16 representation of [^<], encoding is assumed to be UTF-16 with the corresponding endianness (this guess may yield incorrect result, but it's better than UTF-8);
- * Otherwise encoding is assumed to be UTF-8.

Major bugfix release. Changes:
* XPath bugfixes:
- # Fixed translate(), lang() and concat() functions (infinite loops/crashes)
- # Fixed compilation of queries with empty literal strings ("")
- # Fixed axis tests: they never add empty nodes/attributes to the resulting node set now
- # Fixed string-value evaluation for node-set (the result excluded some text descendants)
- # Fixed self:: axis (it behaved like ancestor-or-self::)
- # Fixed following:: and preceding:: axes (they included descendent and ancestor nodes, respectively)
- # Minor fix for namespace-uri() function (namespace declaration scope includes the parent element of namespace declaration attribute)
- # Some incorrect queries are no longer parsed now (i.e. foo: *)
- # Fixed text()/etc. node test parsing bug (i.e. foo[text()] failed to compile)
- # Fixed root step (/) - it now selects empty node set if query is evaluated on empty node
- # Fixed string to number conversion ("123 " converted to NaN, "123 .456" converted to 123.456 - now the results are 123 and NaN, respectively)
- # Node set copying now preserves sorted type; leads to better performance on some queries
