Version 3.18.2 is from 2015. The newest version is 3.34.1. See 
https://wiki.gnome.org/Apps/Evince/Downloads for links to the official 
downloads.

As far as I know, the dvi backend has never supported the text 
interfaces. Only the PDF and DjVu backends currently support it.

There very well may be a bug in evince, though since text selection is 
working fairly well with PDF documents, if there is a bug, it might be 
limited to only the DVI backend.
