If I interpret correctly the spec, the exception should be in the form
"with keywords exception", where keywords can be "Font" and "OpenSSL"
or any other keyword if new permissions are granted.

cme will allow any keyword to be used, but requires the "exception"
word at the end of the sentence.

In your case, you can try 'GPL-3+ with Font-exception-2.0 exception'.

All the best
