To repeat what I said last time:

On Linux/*nix a filename path is just a bunch of bytes. It may be in any
(8-bit) encoding, ISO-8859-X, UTF-8, whatever. You need to acquire the
filename/filepath in the file system encoding or convert it to the
encoding used. It's a bit of a mess, esp. with the python layer on top,
but I'm sure there are docs somewhere that explain it in more detail.
Then you need to create a URI from that file path. Prefixing it with
'file://' may sometimes work, but is not correct and won't work with
relative paths either.

GStreamer (on Linux) expects a URI that expresses the file path in file
system encoding. This isn't necessarily UTF-8, but might be. (We don't
know.)
