There is no such thing as "junk characters" or "junk values" -- period. Each and every character has a valid value in the collating sequence. The characters may not be printable but that does not mean they are "junk".
You should browse or edit the data set in hex mode so you can see precisely what the non-printing characters actually are. Once you know what they are, you can devise a way to remove them.
