How did you come up with the name? Especially the "_he-IL" part? I mean, why not just 0408_freetextlua.vfb like all other languages?
Or do I have the wrong original files? Because in the files I have, all languages have just <country id>_freetextlua.vfb.
For some reason line choice (only that) does not work for me, whether I name the file like you said or just 0408_freetextlua.vfb
