Assuming you're already using rxvt-unicode, put this in your urxvt-perl directory and add "unichr" to "perl-ext". For instance, I have:
URxvt*perl-lib: /home/jepler/.urxvt-perl URxvt*perl-ext: unichr,matcher,-selectionand unichr is in /home/jepler/.urxvt-perl/unichr
After 'installation', open a fresh terminal, press shift+ctrl+u and then enter the unicode code point in hex, then hit enter. e.g., C-S-u 221e types ∞.
