'utf8' codec can't decode byte 0xe7 in position 8: invalid continuation byte

Hi, after i extracted homedir to public_html i tried to open public _html directory.
But i get this error “‘utf8’ codec can’t decode byte 0xe7 in position 8: invalid continuation byte” message at bottom right side in a red box.
