Bug - Non-Ascii character in branch name causes worker to crash
<!-- Make sure the title starts with "Bug - [insert short description of bug]" -->
## Description
If there is a non ascii character in the branch name, the Unzipper will not work and causes the worker to crash.
## Priority - High
The project can no longer be analyzed. If a student uses any strange character as a folder name (which is somewhat likely) the worker will crash. This is undesirable
## Definition of done
When the worker can unzip a zip containing a non-unicode character.
