This thread is resolved. Here is a description of the problem and solution.
Problem:
The client wants to display the permalink of the Japanese page in English instead of Japanese characters. Currently, the URL shows Japanese characters, which they want to change to English.
Solution:
First, ensure that the WPML settings are correctly configured to copy the permalink from the original language if the translation language uses encoded URLs. You can check and adjust these settings under WPML->Settings->Page URL. Additionally, set the encoding URL option for Japanese to 'YES' under WPML->Language->Edit Languages.
If there are mixed parts in English and Japanese, you will need to resend the content for translation to ensure all parts are correctly updated.
We also recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
