Another feature I need a lot is the correct interpretation
of CJK encoding.

Yes, I know PDF can be a pain when it comes to
correctly interpreting CJK charsets, as many factors are
involved, including whether a font (or its subset) is
embeded or not.

Attached is a simple Korean PDF that so far has not
been correctly interpreted by any java based
opensource libraries. Though it could be rendered
correctly by XPDF on linux and also Windows.

Hello Ben,

Thanks for the response. I just downloaded PDFBox 0.6.5 and
wrote a little sample program to test it against 3 CJK PDF files
I have, and the output is still no good. I have attached my
sample program, the 3 PDFs and the output in the attached
zip file.

Can you tell me what I am foing wrong?

The PDF files were generated by using Adobe Acrobat 5.0
using embeded fonts I believe.

Thank you.

There was no attachment with this. I have done some CJK
work in the 0.6.5 release. Please attach the document and I
can take a look at it.(Make sure you check the 'attach file'
checkbox)

Ben
