Yeah just added To: so that you really know someone mention you.

Yeah it would be prefered that before this gets Linus tree then this
will use iocharset. Because this driver will probably replace NTFS
driver some day I think it is still good idea to make nls= alias. And
also because Paragon's own customers will might use it and there is
already many many users who uses ntfs3 because it is included some "must
have kernel patch lists".
