The first problem is bidi related: Try: (describe-input-method 'arabic) and then try: (describe-input-method 'hebrew) In the case of 'arabic note how the entire keyboard is flipped to the right. The second problem is shaping related: Inside of a cell on the keyboard layout, when there are two characters that can be joined, they are joined -- be default. They should not be. Consider for example غإ which should have been غ‌إ instead. The fix can involve inserting a (ucs-insert 8204)‌ between the two characters in each cell. That is a ZERO WIDTH NON-JOINER. I can help with this and work with maintainer of describe-input-method to add the above changes. Good input methods help/documentation for bidi languages are important when emacs24 comes out. Thanks. ...Mohsen
