rxvt-unicode is a modern, Unicode-aware color xterm replacement that uses significantly less memory than a conventional xterm and many other Unicode supporting terminal emulators.
It supports using multiple fonts at the same time, including Xft fonts, and client-server technology to reduce memory consumption when using multiple windows.
This package is configured with 256-color support, and TERM set to "rxvt-unicode-256color". Any other systems you log into must have this terminfo entry installed!
