This is a nasty bug which also regularly appears in the forum and I could never reproduce it.

However, for me it doesn't corrupt Py_Initialize but it much later throws an exception in the built-in script at the line:
os.environ["PATH"] = PathExtension + os.environ["PATH"]

You can also demonstrate this problem directly in Python.
1. Open a terminal and enter e.g.: set PATH=%PATH%;C:\Temp\äöü
2. Start a Python session with python.exe
3. In the Python prompt enter:
import os
"test"+os.environ["PATH"] ## => nothing happens
4. Now enter this:
u"test"+os.environ["PATH"] ## => UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in position 734: ordinal not in range(128)
