SIL International is an evangelical Christian non-profit organization whose main purpose is to study, develop and document languages, especially those that are lesser-known, in order to expand linguistic knowledge, promote literacy, translate the Christian Bible into local languages, and aid minority language development.
Arial Unicode MS is a TrueType font and the extended version of the font Arial. Compared to Arial, it includes higher line height, omits kerning pairs and adds enough glyphs to cover a large subset of Unicode 2.1—thus supporting most Microsoft code pages, but also requiring much more storage space. It also adds Ideographic layout tables, but unlike Arial, it mandates no smoothing in the 14–18 point range, and contains Roman (upright) glyphs only; there is no oblique (italic) version. Arial Unicode MS was previously distributed with Microsoft Office, but this ended in 2016 version. It is bundled with Mac OS X v10.5 and later. It may also be purchased separately from Ascender Corporation, who licenses the font from Microsoft.
Gentium is a Unicode serif typeface designed by Victor Gaultney. Gentium fonts are free and open source software, and are released under the SIL Open Font License (OFL), which permits modification and redistribution. Gentium has wide support for languages using the Latin, Greek, and Cyrillic alphabets, and the International Phonetic Alphabet (IPA). Gentium Plus variants released since November 2010 now include over 5,500 glyphs and advanced typographic features through OpenType and formerly Graphite.
Junicode ("Junius-Unicode") is a free old-style serif typeface developed by Peter S. Baker of the University of Virginia. The design is based on a 17th-century typeface used in Oxford, England.
There are Unicode typefaces which are open-source and designed to contain glyphs of all Unicode characters, or at least a broad selection of Unicode scripts. There are also numerous projects aimed at providing only a certain script, such as the Arabeyes Arabic font. The advantage of targeting only some scripts with a font was that certain Unicode characters should be rendered differently depending on which language they are used in, and that a font that only includes the characters a certain user needs will be much smaller in file size compared to one with many glyphs. Unicode fonts in modern formats such as OpenType can in theory cover multiple languages by including multiple glyphs per character, though very few actually cover more than one language's forms of the unified Han characters.
Graphite is a programmable Unicode-compliant smart font technology and rendering system developed by SIL International as free software, distributed under the terms of the GNU Lesser General Public License and the Common Public License.
The DejaVu fonts are a superfamily of fonts designed for broad coverage of the Unicode Universal Character Set. The fonts are derived from Bitstream Vera (sans-serif) and Bitstream Charter (serif), two fonts released by Bitstream under a free license that allowed derivative works based upon them; the Vera and Charter families were limited mainly to the characters in the Basic Latin and Latin-1 Supplement portions of Unicode, roughly equivalent to ISO/IEC 8859-15, and Bitstream's licensing terms allowed the fonts to be expanded upon without explicit authorization. The DejaVu fonts project was started with the aim to "provide a wider range of characters ... while maintaining the original look and feel through the process of collaborative development". The development of the fonts is done by many contributors and is organized through a wiki and a mailing list.
Charis SIL is a transitional serif typeface developed by SIL International based on Bitstream Charter, one of the first fonts designed for laser printers. The font offers four family members: roman, bold, italic, and bold italic.
The SIL Open Font License is one of the major open font licenses, which allows embedding, or "bundling", of the font in commercially sold products.
Linux Libertine is a digital typeface created by the Libertine Open Fonts Project, which aims to create free and open alternatives to proprietary typefaces such as Times New Roman. It is developed with the free font editor FontForge and is licensed under the GNU General Public License and the SIL Open Font License.
Liberation is the collective name of four TrueType font families: Liberation Sans, Liberation Sans Narrow, Liberation Serif, and Liberation Mono. These fonts are metrically compatible with the most popular fonts on the Microsoft Windows operating system and the Microsoft Office software package, for which Liberation is intended as a free substitute. The fonts are default in LibreOffice.
Nimbus Mono is a monospaced typeface created by URW Studio in 1984, and eventually released under the GPL and AFPL in 1996 and LPPL in 2009. In 2017, the font, alongside other Core 35 fonts, has been additionally licensed under the terms of OFL. It features Normal, Bold, Italic, and Bold Italic weights, and is one of several freely licensed fonts offered by URW++. Although not exactly the same, Nimbus Mono has metrics and glyphs that are very similar to Courier and Courier New.
Ubuntu is an OpenType-based font family, designed to be a modern, humanist-style typeface by London-based type foundry Dalton Maag, with funding by Canonical Ltd. The font was under development for nearly nine months, with only a limited initial release through a beta program, until September 2010. It was then that it became the new default font of the Ubuntu operating system in Ubuntu 10.10. Its designers include Vincent Connare, creator of the Comic Sans and Trebuchet MS fonts.
Arabic Extended-A is a Unicode block encoding Qur'anic annotations and letter variants used for various non-Arabic languages.
Noto is a font family comprising over 100 individual fonts, which are together designed to cover all the scripts encoded in the Unicode standard.

In total, Noto fonts cover nearly 64,000 characters, which is under half of the 149,186 characters defined in Unicode 15.0.
Theano Didot is a free and open-source typeface by Alexey Kryukov, released under the Open Font License (OFL) in 2007. It is a revival of the Didot typeface of Firmin Didot, in the Didone or modern serif genre of the early nineteenth century.
