I believe the relevant source code is this:
http://svn.gnu.org.ua/viewvc/gentium/trunk/gentium/source/fonts/gentium-tug/lig/gentium-agr.lig?revision=4&view=markup

The author of that file is no longer using 8-bit encodings.
Are you perhaps able to figure out the patch and test it? I'm not even
sure what boundarychar is.

The list of characters could be found here, for example:
http://svn.gnu.org.ua/viewvc/gentium/trunk/gentium/fonts/afm/public/gentium-tug/GentiumPlus-R.afm?revision=21&view=markup
