WordPress SEO version: 1.1.6 / 1.1.7
I did this: Created a new post with unicode characters in title.
I expected the plugin to do this: Create the slug, replacing the unicode chars with the corresponding letters.
Instead it did this: Created the slug from the post without the unicode characters being replaced by the corresponding letters. Instead it deleted those letters.
If we modify the slug after it's auto generated, and we let it auto generate again, all is ok.
