--As of Thursday, April 1, 2004 9:58 AM -0500, [EMAIL PROTECTED] is 
alleged to have said:

Is there a simple way to reject any string that has extended characters
in  it? In other words, only accept the 88 (I think it's 88) regular
keyboard  characters and numbers. I can't find a simple way to do this.
--As for the rest, it is mine.

I'm sure there is a smart way, but here's a dumb idea:

my @characters = unpack('U*', $string);
for @characters {
   if $_ > $max_Char_Value {
   # Do something
   } else
   # Do something else.
   }
}

Please send two sample strings one that contains 'reject'able stuff, and other with 
those 88. That would clarify us better.

Does this help?
 if($string !~ m/^\w+$/) { die "I hate extended characters"; }
Of course \w+ is letters , numbers, and underscores only, you will need 
to add any other characters you want tot he regex but that should get 
you started eh?

if ( $string =~ /[^[:print:]]/ ) {
print "This string has invalid characters in it.\n";
}
