Thanks, applied as #31796 (although I'm not sure why it
works)

The Win32::SetCwd causes INC (which contains ../lib)
to be "bad".  It
appears that Win32::GetLongPathName needs utf8.pm, but
couldn't find
it after the dir change.  The patch grabs the values of
Win32::GetCwd
needed for the test, changes back to the original dir, and
then does
the test.

Slight correction.  It's not Win32::GetLongPathName that
needs utf8.pm, but rather Test.pm when it tries to complain
about the test failing as the paths involved have Unicode
chars.
