Virtualenv installation failure due to U+0441 character

[acolley]

OS = Windows 10
Shell = PowerShell
Python = 3.8
Version = current master HEAD: 94bb422

While installing the library into a virtualenv I encountered the following error:

According to the output this appeared to be caused by a unicode U+0441 character in the protoactor-python.cluster module name.

I saw that the module protoactor-python.cluster module was duplicated. This is presumably because of the U+0441 character used in place of the c character in one of them. I removed the directory with the unicode character and left the other directory intact.

After removing the virtualenv, re-creating and running pip install . again the operation failed with a similar error:

This was due to the U+0441 character in the remaining protoactor-python.cluster module's cluster.py module name.

After renaming this module to use c instead of U+0441 the installation completed successfully:
