IE_Imp_Text_Sniffer::UCS2_Endian IE_Imp_Text_Sniffer::_recognizeUCS2	(	const char *	szBuf,
		UT_uint32	iNumbytes,
		bool	bDeep

UT_Error IE_Imp_Text_Sniffer::constructImporter	(	PD_Document *	pDocument,

const IE_MimeConfidence * IE_Imp_Text_Sniffer::getMimeConfidence ( ) [virtual]

Implements IE_ImpSniffer.

const IE_SuffixConfidence * IE_Imp_Text_Sniffer::getSuffixConfidence ( ) [virtual]

Implements IE_ImpSniffer.

UT_Confidence_t IE_Imp_Text_Sniffer::recognizeContents	(	const char *	szBuf,
		UT_uint32	iNumbytes
	)			`[virtual]`

Check if buffer contains data meant for this importer.

We don't attmpt to recognize since other filetypes (HTML) can use the same encodings a text file can. We also don't want to steal recognition when user wants to use the Encoded Text importer.
