Spleen is the default OpenBSD terminal console font. It's been recreated as a monospaced bitmap font for use elsewhere. Each size is provided in the Glyph Bitmap Distribution Format (BDF), and release tarballs contain the fonts in the following formats: PCF, PSF (for the Linux console), OTB, OTF, .dfont for macOS users, and FON for Windows users. All font sizes contain all ISO/IEC 8859-1 characters (Basic Latin and Latin-1 Supplement Unicode block), Latin Extended-A characters, as well as Box Drawing, Block Elements, and Braille Patterns Unicode blocks, except for the 5x8 and the 6x12 versions.
