That���s hard to do, but name a file in an encoding other than
'filesystem' on an NTFS filesystem.  What I did was accidentally
create a file whose name was encoded in UTF-16.  Then, do
Dir['dir'].entries.each{ |e| printf "%p: %s\n", e, File.file? e },
where 'dir' is the directory containing this file.  e.file? will
return false for this file, even though it���s a file.  The problem is,
as explained, in rb_stat(), as it re-encodes its argument in the
'filesystem' encoding.
