Question

Does anyone knows how to detect printable characters in java?

    public boolean isPrintableChar(

I'm not perfectly sure whether I understand your problem. But if you want detect if character can be drawn to Graphics object, and if not print some placeholder char you might find usefull:

Font.canDisplay(int)

It will check whether font can display specific codepoint (it is more that check whether font is displayable at all -- since there are chars that are displayable - like ą - but some fonts cant display them.
