File talk:Setham Ayin 2.jpg

The description says "The Hebrew letter ע in Setham writing." but there is no explanation, what "Setham" refers to, nor is there a wp article with that name. Even after quite a while of searching, I could not find ANYTHING about the word "Sethan" except, that it'a a family name (?).

It also seems that most references name the symbol shown in the graphic "Ayin4" and not Ayin2.

Could someone knowledgeable in this language please elighten me? :-)

P.S.: Is this char supposed to be in Unicode?
