Some fonts need differently designed accents for uppercase letters. Due to the limited space available above the uppercase, accents may need to have a low profile compared to accents above the lower case.

I have added definitions for low profile accents to the Complete Composites feature. New definitions have been added for:
57365 • Low Profile Grave
57366 • Low Profile Acute
57367 • Low Profile Circumflex
57368 • Low Profile Caron
57369 • Low Profile Tilde
57370 • Low Profile Double Grave
57371 • Low Profile Double Acute
57372 • Low Profile Breve
57373 • Low Profile Inverted Breve
57374 • Low Profile Ring Above
57375 • Low Profile Profile Hook
57376 • Low Profile Diaeresis
With the update to FontCreator 5.6, the CompositeData.xml files for version 5.5 have become obsolete. Any future updates will be only for the most recent version, so if you haven’t updated your copy yet, do it now.
To add low profile diacritics to your fonts
- Insert characters 57365-57376 to add the mappings
- Complete Composites to add the accents
- Decompose the new accents and redesign them to suit uppercase, but still position them for lowercase
- Complete composites will now use them by default, if they exist, but will use regular accents if they don’t.
CompositeData.xml was updated for FontCreator 5.6. There have been major improvements to the Complete Composites feature in this version, which are documented in this PDF attached to this post.
For a less technical summary of all of the main changes in the new version, see my FontCreator Review (in my sig).
