* Summary: interface for the encoding conversion functions
* Description: interface for the encoding conversion functions needed for
* XML basic encoding and iconv() support.
*
* Related specs are
* rfc2044 (UTF-8 and UTF-16) F. Yergeau Alis Technologies
* [ISO-10646] UTF-8 and UTF-16 in Annexes
* [ISO-8859-1] ISO Latin-1 characters codes.
* [UNICODE] The Unicode Consortium, "The Unicode Standard --
* Worldwide Character Encoding -- Version 1.0", Addison-
* Wesley, Volume 1, 1991, Volume 2, 1992. UTF-8 is
* described in Unicode Technical Report #4.
* [US-ASCII] Coded Character Set--7-bit American Standard Code for
* Information Interchange, ANSI X3.4-1986.

/include "libxmlrpg/xmlversion"
* 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:

* @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.
