I use my device in Japanese and when using my kobo with PDF files, when using a dictionary in words, I cant select the whole word. Long pressing a word, only shows me the definition of one character and not the entire word.

This works with epubs books normally because I can select the word appropriately, however with pdf it doesn't give me an option to select the size of the word. Following is a quick video demonstrating this.
With epubs, regardless of the orientation, I can select the size of the word appropriately. As seen here

Would love to see this fixed since even though I used a PDF file with pictures and selectable text, it doesn't work with a pdf file with pure text.

Thanks in advance and sorry for my poor english.
I think you will be out of luck on this for two reasons.

Firstly, Kobo does not support word selection in PDFs at all. And if you cannot select a word, then you cannot do a dictionary lookup. Though this appears to have changed for at least the Sage and probably the Elipsa. These allow markup in PDFs using the stylus. 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.
