Codec is an ISO-8859-1 encoded sans-serif font in a single height designed for use in writing program code. It is supplied in Bitmap Distribution Format for installation on machines running the X window system. You can't use it under Windows, nor on a Mac.
Codec is available in four variants. Click on the name of each variant for an example.
The original Codec was an experiment applying all the features I thought I might like in a code font. But it turned out I did't really like the proportional spacing or centred full-stop, and Codec Terminal Text is the evolved outcome of lots of actual use.
These fonts were made in 1998. In 2007, Codec Terminal Text is
still my preferred font for writing code, despite the arrival of many
high-quality antialiased fonts in the meantime. It has very few
irritating quirks and a satisfying clarity and sense of space. One
detail I like is that the underscore ("_") rests on the baseline
rather than hanging below it, making underscore_separated_words look
