NO BUG: Post widget and Filter cyrillic characters

Browser: Firefox
OS: Windows

If I create a taxonomy and slug add Cyrillic characters then an error will appear.

Uncaught DOMException: Element.matches: '.%d0%bc%d0%b5%d0%bb%d0%ba%d0%b0%d1%8f-%d1%82%d0%b5%d1%85%d0%bd%d0%b8%d0%ba%d0%b0' is not a valid selector

Thanks so much for your report!

Unfortunately, non-latin / special characters are not supported. WordPress itself has problems with this in slugs. However, there are plugins that at least help with the slugs, but probably not in the posts filter: Cyr-To-Lat – WordPress plugin |

Not an advertisement for the plugin (don’t know it), but the article summarizes the topic very well:

Best regards,

Thanks. I know about this plugin. I thought this was a mistake, since the value from slug should not go directly.
