Table alignment problem

[Fr Ml]

Hello, there is an old problem with table alignment. It's mentioned here: https://emacs.stackexchange.com/q/30495/11498 It occurs as far as I know only in 4 cases (last 4 rows): | 2 latin letters                                 | ab | (2 glyphs)            | | 2 arabic letters                                | من | ok (2 glyphs)         | | same but with 2 diacritics                      | مِنْ | also ok  (2 glyphs)   | | the arabich letter ا and then ل isn't a problem | ال | also ok (2 glyphs)    | | but ل and then ا is a problem (case1)           | لا | not ok (it's 1 glyph) | | also ل and then أ (case2)                       | لأ | " (it's 1 glyph)      | | also ل and then إ (case3)                       | لإ | " (it's 1 glyph)      | | also ل and then آ (case4)                       | لآ | " (it's 1 glyph)      | (screenshot) In the 4 cases two letters build one single glyph and this isn't recognized. That's the problem. I don't know if it's hard to solve but I've noticed for example that orgmode handles the word  مَنْ correctly. It has only 2 glyphs even though this word has 4 characters (2 diacritics+ 2 regular letters). The alignment is correct (3rd row). And unfortunately the 4 mentioned cases occurs very often in Arabic, so the alignment would be much worse with than in the example. I hope this could be solved. Many thanks for the great orgmode features and the bidi support. (Of course I'm using a monospaced font for Arabic. And the problem occurs also if I only use Arabic letters.) Kind Regards Frank
