rxvt-unicode is a clone of the well known terminal emulator rxvt, modified to store text in Unicode and to use locale-correct input and output. It also supports mixing multiple fonts at the same time, including Xft fonts, real transparency, and an optional embedded Perl interpreter that allows you to extend your terminal easily.

Changes:
Calling urxvtc with illegal arguments will no longer crash urxvtd. Xft font drawing has been rewritten to be faster and more correct again (fixing the compose character corruption). The xterm bracketed paste mode extension has been implemented. The RENDER server extension is no longer required for transparency and background pixmaps. The documentation concerning alpha channels in colours has been improved, the "urxvt stays black until the first event arrives" bug has been fixed, and a number of minor cleanups and bugfixes have been implemented.
