They are not mixed up but a correct uri with unicode characters escaped
as per spec [1].

This is correct.

Don't do this, see below how to unescape the uri.

Its your misunderstanding of a uri, see [1].

If you plan to do further processing or monitoring of the file you may
want to look at a glib GFile [2] and use g_file_new_for_uri which will
transparently unescape for you. If you just want to unescape the uri use
g_uri_unescape_string [3].
