OK, that's what is referred to as the old read-only in-tree driver. It
has had experimental write support for a long time, but people still
call it "the read-only driver". Most people "in the know" seem to
advise that the write support should not be used, and many advise not
using that driver it at all. The ntfs-3g FUSE driver is usually
recommended instead.

You need that if you want to use the ntfs-3g FUSE driver.

IIRC, the ntfs-3g driver supports a number features that the old
in-tree read-only driver (which you are using) does not. The
"windows_name" option appears to be one of those.

If you want to use the windows_name option, you'll probably have to
disable the in-tree driver and use the ntfs-3g one. It might be
possible to use ntfs-3g without disabling the in-tree driver, but that
sounds like a good way to get confused...
