jQuery tries to evaluate some CSS classes instead of using as string

[anonymous]

Words such as Естетика are converted to something like .%d0%b5%d1%81%d1%82%d0%b5%d1%82%d0%b8%d0%ba%d0%b0 (CSS class) using popular sanitizers (if you'll use this as WordPress category, it will create such slug/nicename for that category which is supposed to be safe, English version to use in various places in the code).

Although it seems like a valid class name jQuery tries to evaluate that instead of using as a string.

It's not being executed, it's being rejected as an invalid selector. Here is your selector, it appears to be escaped using URL encoding rules:

'.%d0%b5%d1%81%d1%82%d0%b5%d1%82%d0%b8%d0%ba%d0%b0'

Here are the CSS selector escaping rules:

You'll need to escape the selector properly.
