Hi there,
as a follow-up of my investigation into unencoded glyphs, here are some additional observations. There is an IDML (XML) context that isn’t still interpreted correctly. This is the original Indesign text frame containing some glyphs from Cambria Math and the IDML export (CS 5.5):
M-phi-phi-salt.idml
As you can see, I am using the standard phi (Unicode 03C6) from the Greek and Coptic block and phi salt (the common stylistic alternate). The IDML (XML) context for the latter one is:
Publisher doesn’t interpret this context correctly, but displays the standard phi, not the stylistic alternate:
Indesign reimports the file correctly. Please have a look!
