Remove Special Characters From Permalinks

If you are using pretty permalinks, you may have noticed WordPress sanitizes it removing accents and some special characters. However some of these characters are not sanitized by default, meaning they can be added to some of your post URLs, like a trademark symbol(®), a copyright symbol(©) or even a UTF-8 symbol like ⛓. Although it may not hurt you at first, it may let users confused and it can cause some problems when interacting with some third party API that is not prepared to read such characters. This plugin Removes special characters from permalinks when the post is created or updated.
