ArabicText: script for Arabic text flow in AE

UPDATE: Creative Cloud incorporates RTL text in the release of June 2016 (Arabic video; Hebrew demo).



 
UPDATE:  Typewriter effects in After Effects at PVC (August 2013) updates the status of Right-to-Left writing systems like Arabic and Hebrew.

____________________________________

AE Scripts has another script for text manipulation in After Effects, ArabicText, by Salahuddin Taha. Arabic, Hebrew, and other texts are written from right to left, but AE flows letters from left to right in the Composition panel (oddly, the Layer Name stays correct).

TextReverser, from LLoyd Alvarez fixes the flow when the letters are standalone, but broke the letter back into individuals. Arabic is cursive and has medial letterforms, and needed another approach.

Later: There's now an Animation Preset, Typewriter-RTL, that "only works with 2 keyframes that reveal the text from beginning to end."
