Hi, ligature feature depends on font capabilities. It comes with the complex script new feature added in FOP 1.1 (see [1]).
There is an (incomplete) list of fonts that support such feature (see [2]). You can disable such behaviour in 2 ways: - either disable the whole feature (see [3]), - or inserting a ZWNJ where it is relevant (see [4]).
