When user account name contains non-ascii characters such as 'š', such that python executable ends up for example in C:\Users\john.š\.cache\pre-commit\repo\py_env-python3.8\Scripts\python.exe, when committing to the git repository following message appears:

An unexpected error has occurred: AssertionError: BUG: expected environment for python to be healthy() immediately after install, please open an issue describing your environment.

PS: fucntion os.path.isfile() in parse_shebang.normexe() returns False, even though the executable exists there and is a file.
