The Cantarell font family is a contemporary Humanist sans-serif designed for on-screen reading.
The font files currently contain between 647 and 791 glyphs, comprising roughly the Adobe Latin 4 character set, as well as supporting many Cyrillic characters.
These fonts are developed using only Free Software, mainly FontForge. Typeface designs are tools too, so therefore these font files are licensed in a way that respects your freedom — you are invited to extend them to meet your needs, such as to add the glyphs missing from your own writing systems, under the terms of the OFL.
