It would be nice tho, if there was something like a Private Variation
Selector.
Consider for example, a font that offered both of the common glyph
variants of PLUTO. At present, one would be have to be encoded as
U+2647 and the other as a private use character, say U+E647. If a
Private Variation Selector were available, then one could encode
for that font, one form as U+2647 PVS1 and the other as U+2647 PVS2.
Thus, even if the document was then rendered using a different font,
the connection to PLUTO would still be kept no matter which glyph
for PLUTO was used by the author, altho the desired glyph might not
be shown. One could perhaps use the existing Variation Selectors
to do this unofficially, but that is not sanctioned by Unicode. Indeed,
a conforming implementation would have to render them the same
as if no variation selector was present. Perhaps the added variation
selectors on Plane 14 could be turned over to this usage, as it
seems doubtful that they will ever be used for official variations,
or a row of Private Variation Selectors could be added
as U+E01F0 to U+E01FF.
