Refactor path handling in tests for encoded names consistency

- Consolidated multiple lines of code into single statements for improved readability in test cases related to encoded names.
- Updated the logic in various tests to ensure consistent handling of file paths, particularly for encoded module and script names.
- Enhanced clarity in test assertions by streamlining path construction, contributing to better maintainability and understanding of the test suite.
