Detailed Description

JISFileReader Provides a full implementation for an JIS file reader, by supplying the GetNextTextChar method.

Member Enumeration Documentation

enum JISFileReader::JIS_States

States for the JIS state machine.  In the TextImportFilter sample, 

we are only using this to keep track of the current state of the JISFileReader.

For this sample plug-in, we are using the ISO-2022-JP standard.

For more details on the ISO-2022-JP standard and related JIS encodings, refer to the following IETF RFCs:

• RFC 1468: Japanese Character Encoding for Internet Messages, which covers ISO-2022-JP, which includes ASCII, JIS-Roman, JIS C 6226-1978 and JIS X 0208-1983. (http://www.ietf.org/rfc/rfc1468.txt)

• RFC 1554: ISO-2022-JP2: Multilingual Extension of ISO-2022-JP, which extends ISO-2022-JP by adding GB2312-80 and KS X 1001:1992, and by includubg ISO-2022-JP1, as documented in RFC 2237. (http://www.ietf.org/rfc/rfc1554.txt)

• RFC 2237: Japanese Character Encoding for Internet Messages, which covers ISO-2022-JP1, an extension to ISO-2022-JP which adds JIS X 0212-1990. (http://www.ietf.org/rfc/rfc2237.txt)
