Refactor - Remove unicode path encoder properly

Description

After !115 (merged) fixed Unicode handling in Docker containers, the unicode path encoder became obsolete. Due to time constraints, the classes were replaced using cacodi and not removed. This should happen, as it is unused code and can cause confusion later on.

Priority

Low - it no longer runs and can therefore not cause any trouble in production. The only harm is a slight inefficiency and moderate confusion

Definition of done

When the class and its usages are gone
