Thanks for the information.

I know isprint() does not understand SJIS. Now can we hack the code
which accepts one SJIS character? Of course we need to look ahead one
byte to test if the byte sequence is a valid SJIS character.

Does anybody send me the source code of 'strings'? I suppose
it is not a large program.

I think 'no' is too strong word but not impossible. You need to make
some dirty hack :-)
