There is a non-standard alif-lam ligature in the Arabic script. The logo of Al Arabiya shows an example.
Which fonts have such an alif-lam ligature? Should I write U+0627 ZWJ U+0644 to obtain the ligature? Or should I write U+0627 ZWNJ U+0644 to prevent the ligature? Or is alif-lam outside the scope of Unicode and just regarded as a logo?
