The DejaVu fonts are modifications of the Bitstream Vera fonts designed for greater coverage of Unicode, as well as providing more styles. The Bitstream Vera family was limited mainly to the characters in the Basic Latin and Latin-1 Supplement portions of Unicode, roughly equivalent to ISO/IEC 8859-15, but was released with a license that permitted changes. 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.
