App-learning does not support non-unicode in course id

Found a problem that when writing cyrillic in the key fields of the course id (organization, course number, run), it does not open in LMS. In CMS (Studio) courses work fine because I added cyrillic support in mfe authoring

frontend-app-authoring/src/constants.js

export const REGEX_RULES = {
  specialCharsRule: /^[a-zA-Zа-яА-ЯёЁ0-9_\-.'*~\s]+$/u,
  noSpaceRule: /^\S*$/,
};

But I do not see same regex rules in fronted-app-learning.

I undastand it’s because of url parsing. When I click on the link “https://apps.local.openedx.io:2001/learning/course/course-v1:009+ПН1+2024M01/home“ I get to a white page, and logs show

How enable cyrillic in app-learning’s urls

@arbrandes any thoughts here?

This looks like a bonafide problem with the Learning MFE. @Alibek, would you be so kind to open an issue against frontend-app-learning with what you just described?

Okey thanks
