Vera consists of serif, sans-serif, and monospace fonts. The Bitstream Vera Sans Mono typeface in particular is suitable for technical work, as it clearly distinguishes 'l' (lowercase L) from '1' (one) and 'I' (uppercase i), and '0' (zero) from 'O' (uppercase o).
Bitstream Vera itself covers only common punctuation and the Latin alphabet with some diacritics. It comprises only 300 glyphs. Because of its liberal license, the DejaVu fonts project is expanding it with additional glyphs and styles, which it releases into the public domain.
With over 80% installation base, the DejaVu fonts have been gaining on the role as sans-serif default fonts in GNU/Linux. On Windows and Macintosh systems, DejaVu is practically unknown, whereas Bitstream Vera Sans has installation bases of 25% and 20%, and 79% on Unix, according to a survey.
