Yeah, I noticed the same thing when I was looking around. Every one of those is
a bug! It likely works fine for Linux where UTF-8 is common, but they will all
fail on Windows where UTF-16 is used for the OS but `::getenv()` uses the C
locale. Any sort of non-ASCII characters in the file path are likely not going
to do the right thing in that case.
