Good point, thanks!

I committed a slightly modified version of your patch (I merged the if statement with the preceding one) in revision 703273.

> We have some PDF files where the TO_UNICODE map is corrupt and PDFBox cannot extract the text.  font.encode() returns null and PDFStreamEngine.showString() adds the null to the result, which is then printed as "(null)". 
> Here is a patch (against the trunk) that replaces the null with "?".
