Iosevka (IPA: [ˌjɔˈseβ.kʰa]) is a monospace programming typeface, built declaratively using , and with an emphasis on compatibility with CJK characters. It is available under a FOSS license. The default builds are available in two styles of nine weights each, and come with italic and oblique versions. The typeface was designed, however, to be easily configurable by editing textual TOML configuration files in the custom generation software.
