Unicode Characters in the constants.py file are not compatible with Windows

[suppo01]

Describe the bug

The unicode characters in the constants.py file need to be updated as they are not currently compatible with the Windows OS. Because of this issue, when gatorgrade uses gatorgrader, a unicode decode error is thrown which causes the gatorgrader checks to fail.

To Reproduce

Steps to reproduce the behavior:

1. Get inside a repo where gatorgrade can be run on a Windows OS
2. Insure a recent version of gatorgrade is installed
3. Go where the gatorgrade.yml file can be accessed
4. Type gatorgrade into the terminal and hit enter

Expected behavior

A unicode decode error should be thrown by your computer in the yellow diagnostic test under the failures for gatorgrader checks.

Environment

I ran the code using gatorgrade and python. Poetry was present in the repo and ran execexam commands, but it is not related to the bug I described above.

Additional context

I determined that gatorgrade is responsible because when the import for gator, aka gatorgrade, is removed from the file, the unicode decode error is no longer thrown.
