    I've had a request from above to try and see if anyone's done a study to identify ascii chars commonly mistakable for each other? Making our own list isn't a problem, but having some sort of study, etc to point to to say why we did it would be nice. eg: ( and { 0 and O Edit: I have a more extensive list than the two examples I gave, I don't need individual suggestions from the peanut gallery. :rolleyes: MY boss was hoping for an actual study of some sort or the like.

              Perhaps for generating easy-to-read serial numbers?

                      I write all my code in hex so there is no confusion.

                        I've looked for that too but ended up doing my own table for generating passwords, license keys and the like, where you don't want people to confuse characters. I usually use only letters and digits, but I exclude these: I, 1, l (uppercase i, one and lowercase L, respectively) 8, B (problem for us over 45) O, 0, o (oh and zero) Q (tail not visible enough in some fonts) Z, 2 S, 5 So I end up picking random characters from: ACDEFGHJKLMNPRTUVXYabcdefghijkmnpqrstuvwxyz34679 I'm seriously considering removing 6 and b as well - they generate support calls now and then... Later,
