It is sure that there's a possibility that encoding a
filename can't get the original filename. But, Emacs anyway
can't handle such a filename.

A user may type C-x C-f FILENAME in the dired buffer. With
the above method, we don't know how to encode FILENAME.
And, even if one types `f' to visit a file, in that file
buffer, we loose the information of the original
representation.
