hello @yocu
welcome to the forum und thanks for your first participation.
our nc-guidelines and the nc-code-of-conduct kindly ask the user to check for already available solutions on your problem before posting your question on the forum. just to keep the forum as clean as possible.
in your case the searchterm allfontsgen would have gotten you here:
if that won’t help you or if you already did a search on the forum it’s helpful to mention it in your initial posting. as well as some more information about the problematic instance.
good luck
