SEO URL - change special character to english character
Hello, I am vietnamese
In vietnamese has some special character. If title of post is "Đây là 1" => URL of the post http://abc.com/discussion/1/đây-là-1
I Want to change to http://abc.com/discussion/1/day-la-1
The reason is đây-là-1 is not good for SEO.
