Portable Compiled Format (PCF) is a bitmap font format used by X Window System in its core font system, and has been used for decades. PCF fonts are usually installed, by default, on most Unix-based operating systems, and are used in terminals such as xterm. PCF fonts replaced Bitmap Distribution Format due to a slight efficiency increase, however most applications have moved on to scalable fonts.[https://www.x.org/releases/X11R7.7/doc/xorg-docs/fonts/fonts.html Fonts in X11R7.7]
