Here is one strange behavior that i am facing from perl.I have a method which returns a concatenated string value (very large though) given a set of records. String generated inside that method is correct but when i am print the string again outside the method, perl is replacing "#" character with a non printable character (^M, ^C etc). Any idea why it would do this? Code wise here is snippet: 
main ()
{

my $string = foo(@arr);
print "string outside function is " + $string;

}

foo()
{
   //create string
   print "String inside function is " + $string;
   return $string;
}

Output:

string inside function is "abc####123####-6####20111112 ..."

string outside function is "abc####123####-6###^M20111112 ..."

If you observe closely one # is replace by ^M character..Any help would be appreciated. Thanks
