Font Creator 14 Composite issue
This command does not produce the desired result when composite glyphs are generated. However, in the second image below, the composite glyphs were created in Font Creator 13 without any problems. The program also fails to render Arabic composites. An improvement should be made in this regard.
Complete Composites is not enabled yet in FontCreator 14.
Use anchor-based composites instead.
The Complete Composites data only exists for a limited range of characters. In Unicode there are tens of thousands of characters, most of which are undefined. This is a legacy feature from versions of FontCreator that did not support anchor-based composites, so there is not much incentive to add definitions for more character sets now.
Complete composites is now working again with the most recent update.
