If you're using an OS that honors your font choices (i.e., not macOS), you can use a font like Symbola to provide emoji so that they're stylized, monochrome, and vectorized, rather than incongruous color bitmap images. That helps them play nice with terminal colorschemes and things like that.
I'm not aware of any emoji fonts like Symbola which provide a monospace typeface, though. That would be a great option.
