When I specify the home page title in the AIO SEO options page and set it to rewrite titles, special characters (such as ampersands) aren't escaped when output.
You can escape them yourself, but apart from this not being ideal, it doesn't really work. When the options form is output after you've entered the escaped characters yourself, the escaped characters are rendered as actual characters - and if you change another field then update, the home page title field reverts to unescaped characters!
I'm using version 1.5.7.
