But the Problem was: wraped with RLO...PDF ogham is rendered wrong in horizontal text and without it is rendered wrong in vertical text - so one needs to change the explicit directionality when changing from horizontal to vertical and vice versa, but most other combinations of languages do not. That is unsatisfactoring. This was the only reason (as far as I can see) to propose a LR_BT value for the direction. -- Dominikus Scherkl
