'http://localhost/some file.txt' is not a valid URI; you MUST replace
the SPC with either '+' or '%20'. omindex may not be getting all of
this right, but it's the application's job rather than the user's.

('file:"My CV.txt"' is similarly not a valid URI. Again, the
application should be fixing things up somehow.)
