Dear Masters,
I have a exectuable that I capture as array in Perl. The construct looks like this:

 my @output = `./some_executable.out -f $some_param`;

    my %nhash;

    foreach my $output (@output) {

        chomp($output);
        my ( $tm, $val ) = split( " ", $output );

print "BEFORE: $tm\n";
# this regex is not robust because it can't capture «
        $tm =~ s/L//;  
print "AFTER: $tm\n";

        $nhash{$tm} = $val;       

    }

Now, the problem is that in various Linux box the string ($tm) may have different endings:

# sometime this:
$tm = 'fooL';

# other time this:
$tm = 'foo«';

depending on CPU I'm using. My question are:

• is there a universal metacharacter, I can use to remove this sort of line ending?
• what is the cause of this kind of different endings?
