-   BIG5 with its 13494 characters doesn't fit in a single 94x94 or 96x96
-   block. Therefore Emacs/Mule developers, in a typically Japanese way of
-   thinking, have developed an alternative encoding of BIG5 in two 94x94
-   planes, very similar to the SHIFT_JIS encoding for JISX0208.
-
-   Conversion between BIG5 codes (s1,s2) and BIG5-0 codes (c1,c2):
-   Example. (s1,s2) = 0xA140, (c1,c2) = 0x2121.
-   0xA1 <= s1 <= 0xC7, 0x40 <= s2 <= 0x7E || 0xA1 <= s2 <= 0xFE,
-   0x21 <= c1 <= 0x62, 0x21 <= c2 <= 0x7E.
-   Invariant:
-     157*(s1-0xA1) + (s2 < 0x80 ? s2-0x40 : s2-0x62)
-     = 94*(c1-0x21)+(c2-0x21)
-   Conversion (s1,s2) -> (c1,c2):
-     t := 157*(s1-0xA1) + (s2 < 0x80 ? s2-0x40 : s2-0x62)
-     c1 := (t div 94) + 0x21
-     c2 := (t mod 94) + 0x21
-   Conversion (c1,c2) -> (s1,s2):
-     t := 94*(c1-0x21)+(c2-0x21)
-     t2 := t mod 157
-     s1 := (t div 157) + 0xA1
-     s2 := (t2 < 0x3F ? t2+0x40 : t2+0x62)
-
-   Conversion between BIG5 codes (s1,s2) and BIG5-1 codes (c1,c2):
-   Example. (s1,s2) = 0xC940, (c1,c2) = 0x2121.
-   0xC9 <= s1 <= 0xF9, 0x40 <= s2 <= 0x7E || 0xA1 <= s2 <= 0xFE,
-   0x21 <= c1 <= 0x72, 0x21 <= c2 <= 0x7E.
-   Invariant:
-     157*(s1-0xC9) + (s2 < 0x80 ? s2-0x40 : s2-0x62)
-     = 94*(c1-0x21)+(c2-0x21)
