Does the glyph have any outline overlaps? Are the outlines in the correct direction? Have you tried running CheckOutlines?
any idea what could be the cause that hinting (fontlab autohinting + AFDKO) "hides" (blanks) the ffi ligature in one of my fonts?
When I hint my font and then export it to opentype postscript-flavoured, the ffi-ligature glyph is just white. all other glyphs work fine.
When I don't hint at all, the ffi glyph is visible as well.
I just tested in Indesign CS2 until now, but maybe someone knows what could be the cause for this?
Thanks
Sebastian
