How to Copy & Paste text from Chinese text PDF?

[E-Books]

I am unable to extract the Chinese language text (in the same way how it appears) from editable PDF through the option "Copy & Paste and Save as RTF/Doc" in Acrobat 9 Professional.

This is actually font embedded text PDF (Used: type 1 fonts & custom encoding) and not scanned PDF. I found only the garbled text when "Copy & Paste" (or save as RTF) rather than actual Chinese text (Please refer the attached Screenshot 1).

I had also tried to extract the font embedded into the PDF to render the extracted (copied) text properly but not succeeded (i.e font files were extracted but which were not working). Also attached the sample PDF for your reference.
Note: I do not want OCR because I need to proofread and make corrections if any error found.


If anybody can offer any suggestion that will be greatly appreciated.

Just got a PDF Converter.
Try this ZAMzar:http://www.zamzar.com/
Well, I have well experience with Cisdem PDFConverterOCR, it can extract contents out of different languages PDF, it's only got a mac version, but I think you are on Windows, right?

Thanks for the reply.
I have tried the link http://www.zamzar.com/ and found only the garbled text (Refer below)

Example text:
------------------------
; È ›ÙÚÛ=ÜÖ × Ý
É ¦3§¡Ñ¨T Þ^—%ø š-…ó‰ßº1¦3§àEÏ;
ñ16S¶·N¾É¿3áâ ¦3§ãH—±Ð×°±›ä1+ v å0 æçÜ „ó©ªdPèóé'/ê kcëÖäÏ¿œìí§ (
!"#$%&'( )*+,
------------------------

And moreover, I am not interesting in OCR as the source is text PDF and OCR requires manual proofing & correction but which is not a easy job because of Chinese language.

I guess the "custom encoding" is the problem. The copied text would come in that custom encoding. Can you extract the font, copy-paste the text and display it with the extracted font?

Exactly right. If you are copying and pasting Chinese text into MS Word, the font encoding needs to be correctly mapped to Unicode-16 characters. This PDF's encoding is not. You would have to figure out how the encoded characters map to Unicode-16 and write a mapping filter.
