Further more PDF is not exactly a ebook-format.
It was and is designed to exactly represent the layout of a printed page.
But it is no where written, that a word, a sentence or paragraph are stored in a "readable" order within (even a textbased) PDF-File.
So a singel word could be composed out of single letters in no particular order. Only the coordinates given to the letters, compose the word in the layout.
This giving the reader/dictionary software no clue where to start or stop the word.
