Hi!
A client is reporting a crash when using the font in Adobe InDesign server within Stibo environment.
From what I’m gathering the issue revolves around this :
CFF charset off-by-one bug — InDesign crash on Polish text
When exporting an OTF from Glyphs 3, the CFF charset includes .notdef explicitly at index 0, giving 835 entries instead of the correct 834 (.notdef should be implicit per the CFF spec). As a result the cmap is also off-by-one, mapping Polish characters like U+0105 (ą) to wrong glyphs — which causes InDesign to crash during table recomposition.
Font has 835 glyphs, .notdef is at GID 0 with export enabled, no DisableAllAutomaticBehaviour or Don't use Production Names set.
Any idea what could be causing this?
Many thanks in advance!
