Search for Quotation Marks Problem

If you search for a quotation mark and “Whole Word” happens to be selected, it will only find the end quotation marks (that is, the curly ones concave to left).

How does it work if you aren’t using smart (curly) quotes? I thought that the two sets of curly quote marks have different codes, while regular (straight) marks have the same code for the opening or closing quotes. I could be wrong about that.

When you’re doing a search, do you simply type in the quote marks or do you copy and paste the opening or closing marks into the search box?
