Xterm is a little behind the curve in some areas. For example I'm not sure that it properly handles color emoji -- and many modern hipster dev tools of the sort likely to shit ANSI color codes to stdout without even bothering to check if stdout is a tty, are also prone to using emoji for things like checkmarks for passing tests. (Homebrew, in particular, uses U+1f37a, BEER MUG, to indicate it has completed operations.) But maybe you don't care about that. 90% of the time, I don't.
