This PKGBUILD builds urxvt-unicode with the patch from https://github.com/blueyed/rxvt-unicode/tree/display-wide-glyphs to display glyhps that are too wide instead of a square.
urxvt considers the font to be broken, e.g. if the glyph is wider than the
number of cells that wcwidth(3) reports. This gets better with Unicode 9
(since e.g. more characters are assigned a width of 2), but it does not help
with characters from the Private Use Area (e.g. Font Awesome).
I am coming back to this approach after blueyed/rxvt-unicode#1 turned out to be too fragile:
- the method of using a socket for communication fails for remote applications, and already when re-attaching to a tmux session after closing the terminal it was started from (where the terminal cannot respond to requests on the socket then anymore).
- using OSC terminal escape sequences also does not work with tmux (server), and other applications that have no tty attached.
