I didn't know there was a Unicode code point for that! I'd always thought one should just use straight quotes for inches. Thanks!

That was exactly the reference I turned up—though I (shamefully) didn't read far enough to see the mention of proper foot and inch marks, only the initial recommendation to use straight quotes.
