Would it be good to have a new table which is similar in structure to a 
GSUB table but which can have in the part to the left of each -> either 
one postscript name or a sequence of postscript names and to the right 
of each -> a string of Unicode text characters in UTF-16 format - that 
is, a string of text characters as one might have in, say, a computer 
program written in Pascal, for the avoidance of doubt specifically not a 
sequence of postscript names.

I am thinking that this could have various uses, for example, for text 
to speech in a language of the font designer's choice, transliteration, 
on-screen explanation of emoji - including perhaps the potentially 
millions of QID emoji that may soon become encoded into Unicode, so that 
a font that supports just a few QID emoji could also include an 
explanation of them in a language of the font designer's choice. The 
output of the table could be used for any of screen display, tooltip 
display, speech output. The use of the table in a font would be optional 
and could be simply ignored by an application that does not support it: 
also an application that does support the use of the information that is 
in the table could have a button to switch that use on or off.
