The guidelines were revised, but the results have not been published yet. I
believe this is simply due to no one at Adobe having found the opportunity
to update the website, and not to any late changes.
My understanding, based on correspondence with Sairus Patel at Adobe, is
that the existing form
uniXXXX
is now reserved only for BMP characters, derivatives and ligated glyphs, e.g.
uniXXXX.alt
uniXXXXYYYY
For non BMP characters, scalar values are used in the same way but with the
prefix 'u': *
uXXXXX
uXXXXXX
Derivatives are identified in the same way as before:
uXXXXX.alt
but ligated forms must use the underscore indicator as used with AGL names,
in order to avoid ambiguity:
uXXXXX_uXXXXX
uXXXXX_uniXXXX
* The 'u' prefix and ligating indicator can be used for BMP characters
also, but since some existing software already parses the uniXXXX form
names it is probably best to stick with these for the BMP. The 'uni' prefix
will only be interpreted as a BMP character, BMP derivative or ligation of
BMP characters.
I will try to find out from Sairus when Adobe might be updating this
information.
