Words with apostrophes don't get automatic links

Love the automatic links section of the Infinite SEO plugin but it doesn't seem to work with apostrophes.

I have categories set up for a number of players using their name as the category name. For instance: Manu Ma’u

When I use this name in a blog post, it's never turned into a link, despite their being a category with the same name.

It's only a problem with names/words that contain apostrophes.
