And to be clear, that means that the *characters* in the document are 
U+05E2 HEBREW LETTER AYIN followed by U+05B8 HEBREW POINT QAMATS, and 
the "alternative ayin" U+FB20 is nowhere to be seen and did not in fact 
need to exist for this to work.  It's just an alternate glyph for the 
character U+05E2.  Unicode encodes characters, not glyphs.
