A DVI to plain text translator capable of generating ASCII, Latin-1, Latin-9 and UTF-8 (Unicode) output, and recognising T1 and other LaTeX encodings (as well as Knuth's original encodings and those of AMS and other fonts). Catdvi aims to become a superior replacement for the dvi2tty utility; the present version outperforms dvi2tty in some areas and is inferior to it in other areas.

The authors are Antti-Juhani Kaijanaho and Björn Brill.
