### Problem

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.

### Solution

Fira Code is a free monospaced font containing ligatures for common programming multi-character combinations. This is just a font rendering feature: underlying code remains ASCII-compatible. This helps to read and understand code faster. For some frequent sequences like `..` or `//`, ligatures allow us to correct spacing.

### What’s in the box?

Left: ligatures as rendered in Fira Code. Right: same character sequences without ligatures.

Fira Code comes with a huge variety of arrows. Even better: you can make them as long as you like and combine start/middle/end fragments however you want!

Fira Code is not only about ligatures. Some fine-tuning is done for punctuation and frequent letter pairs.

Fira Code comes with a few different character variants (`cv01`, `cv02`, etc), stylistic sets (`ss01`, `ss02`, etc), and other font features (`zero`, `onum`, `calt`, etc), so that everyone can choose what’s best for them.

Some ligatures can be altered or enabled using stylistic sets/character variants:

Being a programming font, Fira Code has fantastic support for ASCII/box drawing, powerline, and other forms of console UIs:

Fira Code is the first programming font to offer dedicated glyphs to render progress bars:

We hope more programming fonts will adopt this convention and ship their own versions. Implementation detail: there is no way for programs to detect whether a font h
