The following table explains how shift-JIS codes and KEIS codes are converted.

Table A-2 Specifications for conversion of Shift-JIS and KEIS codes

Shift-JIS code range	KEIS code range	Conversion specifications
		Shift-JIS to KEIS	KEIS to shift-JIS
1st byte: 81 to 9F and E0 to EF 2nd byte: 40 to 7E and 80 to FC	1st byte: A1 to FE 2nd byte: A1 to FE	The Shift-JIS codes are mapped to the KEIS basic character set and extended character set 1.	The KEIS codes are mapped to the shift-JIS standard kanji code area.
1st byte: F0 to FC 2nd byte: 40 to 7E and 80 to FC	1st byte: 41 to A0 2nd byte: A1 to FE	The Shift-JIS codes are mapped to the KEIS gaiji area by using the CommuniNet code mapping utility. For details, see the manual CommuniNet Version 3. Note that the dc_clt_code_convert function converts these codes to spaces.	The KEIS codes are mapped to the shift-JIS gaiji area by using the CommuniNet code mapping utility. For details, see the manual CommuniNet Version 3. Note that the dc_clt_code_convert function converts these codes to spaces.

#1:

These codes are assumed to be undefined kanji codes. The dc_clt_code_convert and dc_clt_code_convert_exec functions convert these codes to spaces or else return an error, depending on the specification of the flags argument.

#2:

These codes are converted to shift-JIS gaiji codes.

However, if the dc_clt_code_convert function is used, these codes are converted to spaces.
