Anonymous Pro (2009) is a family of four fixed-width fonts designed with coding in mind. Anonymous Pro features an international, Unicode-based character set, with support for most Western and Central European Latin-based languages, plus Greek and Cyrillic. Anonymous Pro is based on an earlier font, Anonymous™ (2001), my TrueType version of Anonymous 9, a Macintosh bitmap font developed in the mid-’90s by Susan Lesch and David Lamkins. Anonymous Pro is distributed with the Open Font License (OFL).
A typeface designed for source code.
Fira Code: monospaced font with programming ligatures
Programmers use a lot of symbols, often encoded with several characters. For the human brain, sequences like ->, <= or := are single logical tokens, even if they take two or three characters on the screen. Your eye spends a non-zero amount of energy to scan, parse and join multiple characters into a single logical one. Ideally, all programming languages should be designed with full-fledged Unicode symbols for operators, but that’s not the case yet.
Programming languages are limited to relatively few characters. As a result, combined character operators surfaced quite early, such as the widely used arrow (->), comprised of a hyphen and greater sign. It looks like an arrow if you know the analogy and squint a bit.
