> Raymond mentions Arabic ghayn, but I would expect this to be > transliterated more commonly with U+011F or U+0121. I can assure you that 1E20 and the l.c. companion 1E21 are very clearly used by Wehr in his Arabic Dictionary. As to U+011F or U+0121, I see that Socin, in his old Arabic Grammar (1895), uses U+011F for jim U+062C, and the U+0121 for ghain U+063A. Wright, Arabic Grammar, as old as Socin, also uses U+0121 for ghain U+063A. It may be that these usages of a century ago survive in some quarters even today.
