Here is a sample from the test case I am developing attached. The ..._old.pdf file shows the current fop-trunk behaviour while the ..._new.pdf file shows what happens in the FOP UAX#14 version.
There are quite a few subtle differences (mostly for the better I hope). I also attach the test case file (hasn't got checks yet) if someone would like to study the fo or even better would like to add or comment or improve. Manuel
