Arabic diacritics

[Denis Jacquerye]

You should use ARABIC SHADDA U+0651 in all positions. The presentation
forms (isolated, medial, final forms) are for compatibility with legacy
systems.
See what is said in http://www.unicode.org/versions/Unicode7.0.0/ch09.pdf
about the Arabic Presentation Forms-B.

Cheers,
