+ * It also supports ASCII, ISO-8859-1, and UTF16 (LE and BE) by default.
+ *
+ * Anything else would have to be translated to UTF8 before being
+ * given to the parser itself. The BOM for UTF16 and the encoding
+ * declaration are looked at and a converter is looked for at that
+ * point. If not found the parser stops here as asked by the XML REC. A
+ * converter can be registered by the user using xmlRegisterCharEncodingHandler
+ * but the current form doesn't allow stateful transcoding (a serious
+ * problem agreed !). If iconv has been found it will be used
+ * automatically and allow stateful transcoding, the simplest is then
+ * to be sure to enable iconv and to provide iconv libs for the encoding
+ * support needed.
+ *
+ * Note that the generic "UTF-16" is not a predefined value. Instead, only
+ * the specific UTF-16LE and UTF-16BE are present.
