Interesting.  That matches the output of 'ls -1b' on my Solaris box.
On my linux box (FC4 ppc), it looks like this:

    $ ls -1b
    filea
    fileb
    filec\r

You can run the string through tr(1) to remove any characters you
don't want.  And you can either specify a list to get rid of:

    $ echo $whatever | tr -d "\015"

or list to keep:

    $ echo $whatever | tr -cd a-zA-Z0-9
