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.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).William
