I find "cat -vt" pretty nice for making the invisible and odd more behaved. If they slip you a ^J or comma you are a goner, though:
Code:
$ all256|cat -vt
^@^A^B^C^D^E^F^G^H^I
^K^L^M^N^O^P^Q^R^S^T^U^V^W^X^Y^Z^[^\^]^^^_ !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~^?M-^@M-^AM-^BM-^CM-^DM-^EM-^FM-^GM-^HM-^IM-

If you write a C or PERL app, you can ignore ^j without 2 commas and reverse ignore comma if more than 2, pushing the user id back to a fixed value. Maybe sometimes they cannot determine the user name from id #, and write the binary id # ?
