S with comma/cedilla

I've been trying to pin down what's going on with S comma/cedilla.
As I recall there was confusion over whether character sets like Latin-2
had a comma or cedilla under the S. Currently, my UCS list says

     U+015E LATIN CAPITAL LETTER S WITH CEDILLA

and Latin-2 contains this character. Now, as I recall, the problem was
that this had to actually have a comma below, but the misleading name and
crummy character drawings in ISO 8859-2:1987 caused everyone, including
Unicode, to put a cedilla underneath.

The proposed allocations page has:

     U+0218 LATIN CAPITAL LETTER S WITH COMMA BELOW

Now, my Abobe Glyph List, which this has to agree with, says:

     U+015E LATIN CAPITAL LETTER S WITH CEDILLA = Scommaaccent
     U+1E9E LATIN CAPITAL LETTER S WITH COMMA BELOW = Scedilla
     U+F6C1 LATIN CAPITAL LETTER S WITH CEDILLA = Scedilla (Duplicate)
     
I'm now immensely confused. Is S WITH COMMA BELOW U+0218 or U+1E9E?
Is it the case that Adobe has always had the rendering right, so it's
U+015E is Scommaaccent? Should that not be changed to Scedilla? What's
the sense in U+1E9E being Scedilla?

And then, what is character 10/10 in Latin-2? U+015E, U+0218 or U+1E9E?
Scommaaccent or Scedilla? Help!
