Your test file has the line:

    f = open("lol.txt", "r", "utf-8")

But the third positional argument to the 'open' built-in function is "buffering", which expects an integer. Pass the "utf-8" argument by name instead:

    f = open("lol.txt", "r", encoding="utf-8")

As a side note, you probably also want to join your thread before exiting the script.

Closing here, since it looks as though there's no Python bug.
