parserutils_error hubbub_charset_extract	(	const uint8_t *	data,
		size_t	len,
		uint16_t *	mibenum,
		uint32_t *	source
	)

Extract a charset from a chunk of data.

Parameters

data	Pointer to buffer containing data
len	Buffer length
mibenum	Pointer to location containing current MIB enum
source	Pointer to location containint current charset source

Returns: PARSERUTILS_OK on success, appropriate error otherwise

::mibenum and ::source will be updated on exit

The larger a chunk of data fed to this routine, the better, as it allows charset autodetection access to a larger dataset for analysis.

Meaning of *source on entry:

CONFIDENT - Do not pass Go, do not attempt auto-detection. TENTATIVE - We've tried to autodetect already, but subsequently discovered that we don't actually support the detected charset. Thus, we've defaulted to Windows-1252. Don't perform auto-detection again, as it would be futile. (This bit diverges from the spec) UNKNOWN - No autodetection performed yet. Get on with it.
