Yes, however this will be more complicated than with European languages or Arabic. Unfortunately, I do not have any ready snippets for Japanese, Korean, or Chinese. If I did, I would of course share them.
The snippets I posted on the page you linked are only basic examples and all I wanted was to to show how the developers can programatically overwrite the custom permalinks.
Next, when you automatically create an English page with polylang, the English page will also become an ID, although it is set to postname in parmalinkmanager.
My main language is Japanese, so for SEO reasons, I have no choice but to select an ID. .
Regarding the future, it would be useful if OpenAI could be configured with the parmarink manager plugin, and languages that have SEO problems, such as Japanese, Chinese, and Korean, could be rewritten using OpenAI.
Ok, I see, it is a UI bug. As of now the setting field for “English” is empty, so it uses the default setting %post_id% which is set for main language: Japanese, although the input placeholder displays there %postname%. Please make sure that the English field is not empty here and paste there %postname%:
As regards OpenAI integration, I will implement this in the future if more users would request such feature.
