Whitespace mystery?

[squash]

I have some strings that have trailing whitespaces which this regex is
not matching:

$string =~ s/\s+$//; ## Remove trailing white spaces

I have tried \n and \t but with no luck. What could those whitespaces
be?

Thx!

At this point, we can only guess.

Do us a favor (so that we can help you out). Put the following code in
your program right before your regexp:

print " \$string = \"$string\"\n";
print " $_\n" foreach map ord, split //, $string;

Then give us the output from these two lines. This will help us figure
out what is contained in your $string variable. (You may also want to
put those lines AFTER the regular expression as well, and send us that
output too.)

Thanks for the quick reply! Here's the output:

$string = "VS1 " 86 83 49 160 (before regex)
$string = "VS1 " 86 83 49 160 (after regex)

Thanks, I have figured it out. I added in this line to remove the ASCII
160 characeter for &nbsp:

$string =~ s/\xA0//; ## Remove html &nbsp blank space (A0 hex for 160)
Thx!
