I think you're not testing your code properly: 
$ perl -wE '$_="\01\02"; say length; tr/\000-\007//; say length'

Nothing removed. (Update: But replaced, see Re^5: Illegal character CTRLCHAR code 27) Still you're on the right track. For deleting with tr///, you need a trailing /d: 

$ perl -wE '$_="\01\02"; say length; tr/\000-\007//d; say length'

    Ah ok - thanks for the heads up - have updated my code :) (weird though, as it seemed to get rid of that error I reported in my first post, even without the /d ?)

    Cheers

      Your code was replacing control chars with a space. moritz's is deleting them.
