[Rd] possible bug in "R Editor"

Dear Professor Ripley, I understand that it is not a real reproducible
example, which may require a Chinese OS. I guess that problem is the
routine does not consider the encoding issue by default. If I open an
existing file and save it rather than save a new file, the editor can
handle it appropriately even the file path contains wide characters.
