It never expects that the next char might be "before" the current word. I guess this could also be framed as a RTL problem, but the PDF is a plain PDF, it just seems that Oracle Reports generates these chunks in the reverse order. was: I have the text "10" and "11" and they get merged into to "1110" word.
