The GNU Unifont by Roman Czyborra is a free bitmap font that covers the entire Unicode Basic Multilingual Plane (BMP), using an intermediate bitmapped font format.
It is present in most free operating systems and windowing systems such as Linux, XFree86 or the X.Org Server and some embedded firmware such as RockBox. The font is released under the GNU General Public License Version 2+ with a font embedding exception (embedding the font in a document does not require the document to be placed under the same license).
It became a GNU package in October 2013.
The Unicode Basic Multilingual Plane covers 2¹⁶ = 65,536 code points. Of this number, 2048 are reserved for special use as UTF-16 surrogate pairs and 6,400 are reserved for private use. This leaves 57,088 code points to which glyphs can be assigned. Some of these code points are special values that do not have an assigned glyph, but most do have assigned glyphs.
As of June 2017[update], the GNU Unifont has complete coverage of the Basic Multilingual Plane as defined in Unicode 10.0. Its companion fonts, Unifont Upper and Unifont CSUR, have significant coverage of the Supplementary Multilingual Plane and the ConScript Unicode Registry, respectively. Scripts that are less than 100% complete can be augmented by any contributor.
The large block of about 20,000 CJK ideographs has been copied from WenQuanYi's Unibit font with permission.
