Whoops...
I see that (1) seems that you really do want to test for base
direction (missed that substr 0,1 in the php code...), so my examples
were really irrelevant.
(2) Meir had already made it quite explicit (providing actual code).
Conclusion:
I should never post after midnight, especially when I did not read
all the thread carefuly.
Oh well, at least I got an excuse for my fribidi-py plug (even if that
excuse was irrelevant)...
Apologies, and good night,
Amit
