Arabic scripture in the packet uses plain alef: U+0671 alef wasla becomes U+0627 in the stored ar strings (the blessing and Mark 5, 13 letters), display only, words and vowels unchanged

A device whose fonts lack U+0671 printed it as a box. Only those 13 code points change (0671: 13 -> 0, 0627:
+13); the bold verse is still a substring of the passage. check:packet-strings-parity fails on any U+0671 in
an ar value (it fails on the previous file). The Arabic scripture blocks also name Arabic faces before serif.
