- * Microsoft CP932 is a slightly extended version of SHIFT_JIS.
- * The differences between the EASTASIA/JIS/SHIFTJIS.TXT and the
- * VENDORS/MICSFT/WINDOWS/CP932.TXT tables found on ftp.unicode.org are
- * as follows:
- *
- * 1. CP932 uses ASCII, not JISX0201 Roman.
- *
- * 2. Some characters in the JISX0208 range are defined differently:
- *
- * code SHIFTJIS.TXT CP932.TXT
- * 0x815F 0x005C # REVERSE SOLIDUS 0xFF3C # FULLWIDTH REVERSE SOLIDUS
- * 0x8160 0x301C # WAVE DASH 0xFF5E # FULLWIDTH TILDE
- * 0x8161 0x2016 # DOUBLE VERTICAL LINE 0x2225 # PARALLEL TO
- * 0x817C 0x2212 # MINUS SIGN 0xFF0D # FULLWIDTH HYPHEN-MINUS
- * 0x8191 0x00A2 # CENT SIGN 0xFFE0 # FULLWIDTH CENT SIGN
- * 0x8192 0x00A3 # POUND SIGN 0xFFE1 # FULLWIDTH POUND SIGN
- * 0x81CA 0x00AC # NOT SIGN 0xFFE2 # FULLWIDTH NOT SIGN
- *
- * We don't implement these changes. SHIFTJIS.TXT makes more sense.
- *
- * 3. A few new rows. See cp932ext.h.

- Conversion between SJIS codes (s1,s2) and JISX0208 codes (c1,c2):
- Example. (s1,s2) = 0x8140, (c1,c2) = 0x2121.
- 0x81 <= s1 <= 0x9F || 0xE0 <= s1 <= 0xEA,
- 0x40 <= s2 <= 0x7E || 0x80 <= s2 <= 0xFC,
- 0x21 <= c1 <= 0x74, 0x21 <= c2 <= 0x7E.
- Invariant:
- 94*2*(s1 < 0xE0 ? s1-0x81 : s1-0xC1) + (s2 < 0x80 ? s2-0x40 : s2-0x41)
- = 94*(c1-0x21)+(c2-0x21)
- Conversion (s1,s2) -> (c1,c2):
- t1 := (s1 < 0xE0 ? s1-0x81 : s1-0xC1)
- t2 := (s2 < 0x80 ? s2-0x40 : s2-0x41)
- c1 := 2*t1 + (t2 < 0x5E ? 0 : 1) + 0x21
- c2 := (t2 < 0x5E ? t2 : t2-0x5E) + 0x21
- Conversion (c1,c2) -> (s1,s2):
- t1 := (c1 - 0x21) >> 1
- t2 := ((c1 - 0x21) & 1) * 0x5E + (c2 - 0x21)
- s1 := (t1 < 0x1F ? t1+0x81 : t1+0xC1)
- s2 := (t2 < 0x3F ? t2+0x40 : t2+0x41)
