> I have received encrypted PDF which contains several string objects but not all of them are encrypted.
> I am not sure whether it is or it is not compliant with pdf reference.
> But I have created fix so pdfbox can handle this.
> If string contains only chars between 32-127 then decryption is not necessary (I know, this is not true in 100% of cases but I think it is swallowable)
