I am using your plugin in a french website: c.onfigs/fr and your plugin does not support keywrods with accents.
When the keyword contains an accent, it is compared to the URL and never matched since WordPress slugs remove the accents from post titles.
Note that I have made somme additions to /wordpress-seo/js/wp-seo-metabox.js by forking your GitHub project: http://github.com/gbili/wordpress-seo
Now the plugin supports accents and any Diacritic.
Could you merge my fork to your current version of the plugin, so I don't have to do it on every new version?
Thank you Regards
