--- Comment #8 from Nikolay Sivov bunglehead@gmail.com --- This looks bigger than a test failure on some locale. As far as I can tell, Chr() does depend on host's locale. That's confusing when testing on Windows, because we return user-default locale in tests, and switching system locale does not change it.
What Chr() definitely doesn't do is to use GetACP() the way we do.
