The following document shows the wrong behaviour (the second parentheses is mirrored incorrectly and it should be after the number not before the number).

Assuming "test" is an RTL word when I write (test 1363) I expect to get exactly that but somehow I get (test (1363

One related question: is it possible to change font automatically when luatex sees a LTR word?

Thanks
