We want to remove the chinese characters from the page slug in our second language.
Solution:
Go to WPML -> Settings and set the page url to be translatable. Then, edit the page in the original language and when you edit the translation you will see the slug in the translation editor, and you can add whichever characters you want. Once all slugs are translated, go back to WPML -> SEttings and set the slug to copy from the original when using encoded URLs.
