Why do things like %EC appear in a URL?

A URL may only carry Latin letters, digits and a few symbols, so anything else — non-Latin letters, spaces — is rewritten in a fixed way. That rewriting is what %EC looks like.

Is it safe to remove tracking parameters?

Yes. Values like utm_source and fbclid exist to record where you clicked from, and the link goes to the same page without them. Stripping them makes a shared link tidier.

Does it work on text that is not a URL?

Encoding and decoding do. Splitting into parameters only works on a complete address starting with http://.
