* 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 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.
