not more than
.arg n
single- or double-byte characters from the Kanji string pointed to by
.arg s1
to the Kanji string pointed to by
.arg s2.
The rule of comparison is:
.illust begin
ASCII and numeric characters < Katakana characters < Kanji characters

The &func function returns

an integer less than, equal to, or greater than zero, indicating that
the Kanji string pointed to by

is less than, equal to, or greater than the Kanji string pointed to by
.arg s2.
