With the approach implemented by Simon what gets written to the IF file
is the original sequence, not the mapped sequence. Then when generating
PDF from IF the same code that would generate the synthesized mappings
when generating PDF straight from FO is called to recreate the mappings.
So I don't think we can say there is information about the mappings in
the text nodes.

Ah, I reread your earlier (private) message. I see the problem has to
do with the use of synthesized PUA mappings. Here, the problem really
is that the font should always have a CMAP entry that maps to every
glyph that can be produced by the GSUB process. However, not all fonts
do this, so in the case in point, we have to synthesize some mapping,
from which we have to turn to PUA assignments. This works when we
generate PDF since we generate a subset font that contains the
synthesized mappings. However, I can see that if this is going to IF
instead of PDF/PS, then we need to find a way to recreate those
synthesized mappings.
I think this information is really font-specific, and should not be
tied to specific text nodes though. So if Simon's fix uses text nodes,
then that is probably not the best approach.

I'm presently at W3C WG meetings this week, but I'll try to get on
my schedule. I'm not sure what the IF->PS/PDF problem is, since
the IF->PDF path is clearly working from my tests.

Glenn,
Can you give your opinion about the approach used by Simon? As
I mentioned before (in a private message), the IF -> PS/PDF
route does not work in your original CS patch (for the
languages that CS targets) due to the mapped sequences.
Simon's approach works but requires keeping the original
sequences alongside the mapped ones. I think it is a good
approach but I would like to know if you have a better
suggestion before we apply the patch.
Thanks,
Luis
