Re^2: Collapsing a string to unique characters

No good. Hash keys are unordered.

In the absence of evidence, opinion is indistinguishable from prejudice.

No good. Hash keys are unordered. So? The OP didn't make it a requirement the result was ordered: I have a number of strings, made up only of 64 characters: a-zA-Z0-9/+ . I need to collapse these down to just the unique characters in the string. Besides, Perlmonks has a long tradition of making small changes to the requirements for the sake of winning at golf. ;-)	[reply]

Technically, I should have updated the OP, but I didn't, so if my opinion counts, I'd cut JavaFan some slack. I've learned a LOT from this thread. Thanks to all!	[reply]
