        * glib/giochannel.c: Fixed g_io_channel_seek_position()
        so that G_SEEK_CUR can be used with UTF-8 encoding

        * glib/giochannel.c: Changed test to decide whether
        use_buf is encoded_read_buf or read_buf from
        "if (channel->do_encode)" to "if (channel->encoding)" to
        fix bug 58472

        * tests/iochannel-test.c: Fixed so it doesn't output
        double newlines

        * glib/giochannel.c: Fixed g_io_channel_fill_buffer()
        so that encoded_read_buf is created for UTF-8 encoding
