The permalink works, if you input a correctly encoded URL. But the UI doesn’t make this easy. I’ll see if we can improve it a bit. I have an improvement for permalinks lined up anyway.
Here’s a workaround for now: Create a permalink for /2022/10/03/portproton-%D0%B7%D0%B0%D0%BF%D1%83%D1%81%D0%BA-%D0%B2%D1%82%D0%BE%D1%80%D0%BE%D0%B3%D0%BE-%D0%BF%D1%80%D0%B8%D0%BB%D0%BE%D0%B6%D0%B5%D0%BD%D0%B8%D1%8F%D0%B8%D0%B3%D1%80%D1%8B
Essentially, what you need to do is, put the last part of the URL (“portproton-запуск-второго-приложенияигры”) into a URL Encoder and use the result as permalink (/2022/10/03/<encoded URL part>).
