Is there any way to modify the dialogues? For that matter, can the .k files in the knowledge directory be read/modified? I can't find any information on this anywhere.
There are a couple of mostly-functional udlg editors on teh internets, but you may need to leave the anglosphere to find them, as they are made by french and russian translators.
May I ask why you want to modify the knowledge files?
Similar reasons for why I'm interested in modifying udlg files - typo correction/general small time game tweaking options. (Well, I assume the .k files include item descriptions and the like, anyway, for all that they're wholly unreadable when compiled.)
