How to insert Arabic character for superscript Alef (like in هٰ) and subscript Alef (like in هٖ) from keyboard directly? Are they commonly used in Arabic or only used in Mushaf Uthmani of The Holy Quran?
Actually the subscript Alef is not rendered below ه in my computer (Ubuntu Raring), but on the left side of the letter instead. However the superscipt alef is rendered above the letter.
I doubt I copied a wrong character :) Update: I've checked that it was a not a wrong character, because another machine renders the subscript Alef right below the character, so it was rendering problem in Raring.
