You are allowed to modify the args, they are guaranteed not to be in ROM.
The true signature, if there existed such a thing, should be
unique(char) args. Because D arrays are safe, you are in no danger of
corrupting memory, unlike C.
However, the docs should be updated to add the string variant, I agree
