* XML basic encoding and iconv() support.

* xmlCharEncoding:
*
* Predefined values for some standard encodings.
* Libxml does not do beforehand translation on UTF8 and ISOLatinX.
* 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
* 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.

* xmlCharEncodingInputFunc:
* @out: a pointer to an array of bytes to store the UTF-8 result
* @outlen: the length of @out
* @in: a pointer to an array of chars in the original encoding
* @inlen: the length of @in
*
* Take a block of chars in the original encoding and try to convert
* it to an UTF-8 block of chars out.
*
* Returns the number of bytes written, -1 if lack of space, or -2
* if the transcoding failed.
* The value of @inlen after return is the number of octets consumed
* if the return value is positive, else unpredictiable.
* The value of @outlen after return is the number of octets consumed.
