5x9 and 5x10 are two X11 fonts intended for use with xterm or other programs requiring readable small fonts. At only 5 pixels wide, they are particularly well suited to small laptop screens, allowing two 80 column windows side by side on an 800x600 screen (albeit with no room for window frames), or three windows across with room to spare on a 1280x1024 screen. The fonts implement VT100 line-drawing characters. Bolding is not directly supported; xterm does adequate bolding by duplicating pixels.
The ucs-fonts package contains versions of all the "-misc-fixed-*" and Adobe X Window System bitmap fonts which have been extended to the largest possible Unicode subset that is sensible for these font sizes. These fonts are commonly used with xterm and many other applications. This package also includes a tool to convert these Unicode fonts into other encodings, such as the many ISO 8859 sets.
