    Description

      Subtype is parsed as "Type0" by PDFBox, but parsed as "Type1" by Adobe Reader.
      This is not a bug of PDFBox.
      The reason is TCPDF 4.5.041 generate font AdobeSongStd-Light with bad subtype "Type0".
      It should be "Type1".

      I have test the following codes and they work.
      File: org/apache/pdfbox/pdmodel/font/PDFontFactory.java
      Method: public static PDFont createFont( COSDictionary dic ) throws IOException

      Original:
      else if( subType.equals( COSName.TYPE0 ) )
      {
      retval = new PDType0Font( dic );
      }

      Fixed:
      else if( subType.equals( COSName.TYPE0 ) )
      {
      COSName encoding = (COSName)dic.getDictionaryObject(COSName.ENCODING);
      retval = (encoding!=null) ? new PDType1Font( dic ) : new PDType0Font( dic );
      }

      With such patch PDFBox will act like Adobe Reader.
