U+0082 is not an opening or a closing quote of any kind. It is an ascii control code (Break permitted here). Being invisible is the correct behavior for it. There are almost no fonts that render it. For a list see here:

If you have it in your book, it is almost certainly the result of incorrect character decoding. Simply use search and replace to replace it with the correct character.
