an text-array is filled via a file, but its content should be unique -
that means when the same text is already in the array it should be
ignored. Is there any convenient way to achieve that? The "usual" way
to solve that is not the problem!
I'm guessing the "usual" method is to loop through the text array and then inside the loop build up a new text array that's the original with the duplicates removed. What is it that you're trying to solve? Memory issue, speed? Not ephemerally elegant?
