--------------------------------------------------------------

If you can embed the font as a CIDFontType0 instead of Type1 then PDFBox will be able to find the Hebrew glyphs. Failing that, try creating the field with some placeholder Hebrew text in it - that might trigger Type 0 font embedding.

Once you have that working, you'll need to reorder the Hebrew string visually before embedding it in the PDF, as PDFBox doesn't know about RTL. Java's [Bidi|http://docs.oracle.com/javase/7/docs/api/java/text/Bidi.html] class has a method which can do this for you. Alternatively, try setting PDAcroForm#setNeedAppearances(true) which bypasses PDFBox appearance generation and lets the viewer generate their own appearance for the field - however this can be incompatible with some viewers.
