What to write in slug: transliteration or translation?

Question

Search Engine Optimization

There is a catalog divided into categories. Category is a little 3-5. It is possible to view the catalog by category. The address of such pages looks like this: /catalog/{category_slug}/{page}
Tell me what is better to write in the slug: transliteration of the Russian category name into literal or English translation?
The question concerns only SEO optimization, user-friendliness is not important. in the line, besides this, there are still a bunch of get parameters and no one will remember it.

Answer 1

Write immediately in Russian. Still, the 21st century, utf-8 is everywhere.
