<html> <head> <style></style></head> <body class='hmmessage'><div dir='ltr'> In my own code, I sometimes filter with ((c&0x7F) < 0x20 || (c&0x7F) == 0x7F) to allow accented characters to pass and to avoid using isprint(). I have had bad luck with passing signed chars to is* macros on old systems, plus the whole idea is to avoid passing escapes to xterm, and maybe some locale considers char 27 as printable.<div>Some of the patches call isprint() with a char, and I think that is bad. The man page for isprint on Fedora 17 says that the argument to is* macros must be "unsigned char" or EOF. To be safe, the patches should use isprint((unsigned char)c) or isprint(c&0xFF).</div><div>William</div> </div></body> </html>
