how do make certain that no input (keyboard + mouse paste) is outside
of 7-bit ASCII in a perl script?
The regular expression means that from the beginning to the end of
the (chomped) input is either nothing or a string containing only
characters 32 to 126.
#!/usr/local/bin/perl
use strict;
print "Type something (type 'q' to exit) -> ";
while (<STDIN>){
chomp;
print "Bye!" and last if /^q$/i;
if ( /^[\040-\176]*$/ ){ # all from space to tilde
print "OK. '$_' is all us-ascii\n-> "
} else {
print "Can't accept '$_' ; " .
"contains non us-ascii characters\n-> "
}
}
