Redefinition of "bismillah-ar"

Adding the glyph FDFD to a font is not resolved under the dLig Automatic generation; which shows error

Expected glyph or glyph class

Can you be more specific. What glyphs did you have, what did you add an what exactly do you expect to happen and what is happening?

Try adding the FDFD glyph; which contains components
Then check the features under “Font info”
click update and compile
FDFD in my case shows listed under “dlig”
The Auto generation option cause an error .
I tried a definition of “Symbol” instead of ligaure … but it did not work.
Will send you the file
