Shouldn't a good random number generator create any string (of the appropriate length), including "Mattias Wingstedt (Firefruit)", with equal probablility?
I can easilly recreate the string "P°\221R\1v9V\36ÀÈ<\f\227å\a" (I just did), does this mean that a random generator should never return this string? Should we create a blacklist with strings we can recreate, and check random numbers against it?
