Rename Dialog not handling publisher's quotation marks

Annoyingly, I was sent some files with publisher's quotation marks (aka curly quotes). I usually use the rename dialog to standardize the filenames. I found out today that the rename dialog is not handling the fancier quotation marks automatically. Just in case this is a bug, I thought I'd bring it to your attention.
