.ixfunc2 '&CharTest' &func
.funcend
.desc begin
The &func function tests if the argument
.arg c
is a printable single- or double-byte character.
These are any characters for which the following expression is true:
.millust begin
isprint( c ) || iskana( c ) || jiszen( c )
.millust end
.np
This set of characters includes all printable single-byte ASCII
characters (0x20-0x7E), all single-byte Katakana characters
(0xA1-0xDF), and all valid double-byte characters.
Valid double-byte characters are those in which the first byte falls
in the range 0x81 - 0x9F or 0xE0 - 0xFC and whose second byte falls in
the range 0x40 - 0x7E or 0x80 - 0xFC.
.desc end
.return begin
The &func function returns zero if the argument does not meet one of the above
tests;
otherwise, a non-zero value is returned.
