I solved it myself!
But for those that may stumble upon this question I will post the answer for you.
Seems the coder before me change the font for the specific field and that field does not support special characters.
BaseFont fieldFontRoman =
So i just removed the SetFieldProperty that uses the specific font (for some reason)
So in short you can use a specific font that you do know has it. The other thing is in the PDF Coded creator you must also ensure under properties that all the included/embedded fonts can handle any needed special characters that you might need in the future etc.
Hopes my solution will be of help for any future questions that is the same :-)
