asciiToUTF8: @out: a pointer to an array of bytes to store the result @outlen: the length of @out @in: a pointer to an array of ASCII chars @inlen: the length of @in

Take a block of ASCII chars in and try to convert it to an UTF-8 block of chars out. Returns 0 if success, or -1 otherwise The value of @inlen after return is the number of octets consumed if the return value is positive, else unpredictable. The value of @outlen after return is the number of octets produced.

◆ xmlByteConsumed()

long xmlByteConsumed ( xmlParserCtxtPtr  ctxt)

xmlByteConsumed: @ctxt: an XML parser context

This function provides the current index of the parser relative to the start of the current entity. This function is computed in bytes from the beginning starting at zero and finishing at the size in byte of the file if parsing a file. The function is of constant cost if the input is UTF-8 but can be costly if run on non-UTF-8 input.

Returns the index in bytes from the beginning of the entity or -1 in case the index could not be computed.

xmlCharEncOutFunc: @handler: char encoding transformation data structure @out: an xmlBuffer for the output. @in: an xmlBuffer for the input

Generic front-end for the encoding handler output function a first call with @in == NULL has to be made firs to initiate the output in case of non-stateless encoding needing to initiate their state or the output (like the BOM in UTF16). In case of UTF8 sequence conversion errors for the given encoder, the content will be automatically remapped to a CharRef sequence.

Returns the number of byte written if success, or -1 general error -2 if the transcoding fails (for *in is not valid utf8 string or the result of transformation can't fit into the encoding we want), or

◆ xmlDetectCharEncoding()

xmlCharEncoding xmlDetectCharEncoding ( const unsigned char *  in,
int  len 
)

xmlDetectCharEncoding: @in: a pointer to the first bytes of the XML entity, must be at least 2 bytes long (at least 4 if encoding is UTF4 variant). @len: pointer to the length of the buffer

Guess the encoding of the entity using the first bytes of the entity content according to the non-normative appendix F of the XML-1.0 recommendation.

Returns one of the XML_CHAR_ENCODING_... values.
