FTP directory listing returns empty result if encoding detection or
conversion fails. This CL puts less strict constraint on conversion
so that the whole list can survive some filenames with broken chars
and be shown to users. Other browsers seem to work this way.

The broken chars can happen due to wrong encoding detection, which
cannot be avoided 100%, as reported in the bug.
