> hi, ben , today i found another bug  withe the  type3 
> font.
> you know, the type3 font is used to display some other 
> special "chatacter" exception the ASCII font, for 
> example, the  maths formula, the CJK chararter in some 
> PDF file.  in the PDFont.encode(), it will revoke the 
> following :
> retval = encoding.getCharacter( getCodeFromArray( c, 
> offset, length ) );
> in the  static Encoding.getCharacter( COSName name ),  
> it  should return the charcter according to the cosname. 
> however, in the  encoding.getCharacte() , it will return 
> the cosname when meeting a "special character".
> i think the following code should be comment out:
>         if( character == null )
>         {
>           // it will return the Name to replace the correct 
> chacter.
>            character = name.getName();
>         }

> the PDF file using Type3 Font:
> http://www.census.gov/population/socdemo/race/indian/cp-3-
> 7/tab01.pdf  - the dash character is Type3 font.
> http://www.math.pku.edu.cn/course/probability/download/11.
> pdf - all the Chinese is Type3 font.
> http://ee-wcl.tamu.edu/itw2004/program/yeung_inv.pdf
> you can refer the PDF Reference  version 1.5 page 386.
> http://partners.adobe.com/public/developer/pdf/index_referen
> ce.html
> you can try to copy the text from the adobe reader , and 
> comparing to the result of the PDFBox.  :-)
> certainly, if the Encoding.getCharacter() can return null as i 
> have modified, the code in PDFStreamEngine.showString() 
> should be corrected  as following :
>  if (c!=null) {
>                 stringResult.append( c );
>                 log.info("char="+c);               
>  } else{ 
>              continue;
>  }
