“… a set of matching new libre/open fonts … funded by Canonical on behalf the wider Free Software community and the Ubuntu project. … technical font design work and implementation … by Dalton Maag. Both the final font Truetype/OpenType files and the design files used to produce the font family are distributed under an open licence and you are expressly encouraged to experiment, modify, share and improve.
… in tune with Ubuntu's philosophy which states that every user should be able to use their software in the language of their choice. So … will be extended to cover many more written languages.” — Canonical
