I did a write-up because it was an example of broken text "in the wild" rather than in technical references. Also it takes me a minute to think of () as open/close parens instead of left/right parens.
Unicode is such a complex beast this is just one aspect of it.
I suspect that your user entered the street name correctly at first, then played around with the wrong parenthesis in the wrong locations until he settled upon something that looked like it visually rendered as he expects, on his system in the input box.
