I had to consider the vote for a few minutes.
The title is certainly odd (iterating over a single item?). On inspection, the question is not about the arrays, so the suggested title doesn't fit either.
So, in the end, I think a better title would be "Iterating over characters in a string". And then comes the question of whether it would be worth considering.
I probably would have said no, but given the evident confusion currently, it might actually be worth doing.

Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
