Hi Kiran,
Yes, I have done it before, but that was for multi-lingual sites where I already needed WPML installed. This question is a little different because this is not for a multi-lingual site. It will only be in Japanese. The idea of installing 3 extra plugins that I will only use to translate a single CPT slug is not ideal. I thought it was probably the only way but just wanted to confirm…
If it is the only way, I wonder if this is something that could be considered for the future (allowing more than just lowercase letters, underscore, and hyphen in the CPT slug). I imagine all the people with native languages that don’t fit into just “lower case ASCII” would appreciate being able to keep their single-language sites clean (with minimal plugins) and still get to have CPT slugs in their languages.
Is this a technical limitation or is it something worth putting in a feature request for?
Thanks!
