When doing that, they use a different PDF viewer that apparently allows dictionary lookup for individual words when using your finger. But, it does not allow selection of multiple words or other highlighting. I don't think this PDF viewer is used on the non-stylus enabled devices. It isn't on my Libra H2O running the firmware version 4.33.19608. And it is not used for PDFs with DRM protection.
Secondly, that looks like a PDF made up of images. Unless there is also a text overlay for the text within the PDF, there will be no selection of the text in any application. Without the overlay, the viewer would need to be able to do OCR on the image. That just isn't going to happen in these devices.

Thanks for the reply!
As mentioned before, yea this is a specific PDF generated for text lookups. You can look more into it here

Do you have any idea if theres any customized PDF reader worth installing for this to happen? Because I did try with normal text pdfs and I can select the text with no problem at all when its an English PDF. Seems like this a problem only with Japanese text.
