Correct me if I'm wrong, but doesn't isprint() conform to locale settigs? I don't know if this works with multibyte characters, but for 8-bit locales ls(1) certainly does the right thing, due to a setlocale(LC_ALL, "") call at the very start. > I've added a -w flag to /bin/ls that is used to force raw output > of nonprintable characters when the output is a tty. Other than the above argumet, yes, such a flag could be useful. G'luck, Peter -- This sentence no verb.
