    /// As of GLib 2.20, URIs will always be converted to POSIX paths
    /// (using [`FileExt::path()`][crate::prelude::FileExt::path()]) when using [`AppInfoExt::launch()`][crate::prelude::AppInfoExt::launch()] even if

    /// `U`` and a single URI, `sftp://foo/file.avi`, then
    /// `/home/user/.gvfs/sftp on foo/file.avi` will be passed. This will
    /// only work if a set of suitable GIO extensions (such as gvfs 2.26
    /// compiled with FUSE support), is available and operational; if this
    /// is not the case, the URI will be passed unmodified to the application.
    /// Some URIs, such as `mailto:`, of course cannot be mapped to a POSIX
    /// path (in gvfs there's no FUSE mount for it); such URIs will be
    /// passed unmodified to the application.
    ///
    /// Specifically for gvfs 2.26 and later, the POSIX URI will be mapped
    /// back to the GIO URI in the [`File`][crate::File] constructors (since gvfs
    /// implements the [`Vfs`][crate::Vfs] extension point). As such, if the application
    /// needs to examine the URI, it needs to use [`FileExt::uri()`][crate::prelude::FileExt::uri()] or
    /// similar on [`File`][crate::File]. In other words, an application cannot assume
    /// that the URI passed to e.g. [`File::for_commandline_arg()`][crate::File::for_commandline_arg()] is
    /// equal to the result of [`FileExt::uri()`][crate::prelude::FileExt::uri()]. The following snippet
    /// illustrates this:
    ///
    ///
    /// ```text
    /// GFile *f;
    /// char *uri;
    ///
    /// file = g_file_new_for_commandline_arg (uri_from_commandline);
    ///
    /// uri = g_file_get_uri (file);
    /// strcmp (uri, uri_from_commandline) == 0;
    /// g_free (uri);
    ///
    /// if (g_file_has_uri_scheme (file, "cdda"))
    ///   {
    ///     // do something special with uri
    ///   }
    /// g_object_unref (file);
    /// ```

    /// This code will work when both `cdda://sr0/Track 1.wav` and
