The following table(s) in the font have been ignored by FontForge
Ignoring 'DSIG' digital signature table
The glyph named Omega is mapped to U+2126,
But its name indicates it should be mapped to U+03A9.
The glyph named Tcommaaccent is mapped to U+021A,
But its name indicates it should be mapped to U+0162.
The glyph named tcommaaccent is mapped to U+021B,
But its name indicates it should be mapped to U+0163.
I do seem to have two "Omegas" for some reason -- I assumed that one was for my "Greek" character set, and the other was for math/scientific or something.
And re the T (or t) with the "commaaccent," in FontCreator once again each glyph is there twice, but for each one glyph is named "Tcommaaccent" (or lowercase tcommaccent) and the other it's named "Tcedilla" (or "tcedilla").
I have no idea what the "Ignoring 'DSIG' digital signature table" warning is in reference to (I have no idea what a digital signature table is!).
Should I be concerned about these FontForge warnings?
