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.

How to use it?

All you have to do is saving/updating your post and you will notice special characters will be swiped out from the permalink.

In french, we use unbreakable space and it’s not managed by WordPress. So strange code shows up in permalink, breaking sharing on Facebook by example. This plugin fixes this problem. So 5 stars. Update: I downgrade the rating to 2 stars. There is a conflict with Markdwon Module in Jetpack and there was no update made. Too bad. Update : after contact through Facebook page, the problem has been fixed. Hooray. So back to 5 stars.

I’m from Viet Nam, My project encountered a problem with permalink that had special characters or emoticons that I could not fix, websites that were available to many users. They do not know edit url manually, so this plugin is a relief for me Thanks so much!
