You *do* realise that I had to open an Imgur account for this. I hold you responsible for the consequences :-)
The colours here are my own custom colours (I need more contrast than stock because I have poor vision). Also you will note the HUGE font. Also because I have poor vision. I decided not to change the size of the images just so you can see how nice it looks with antialiased fonts. Finally the bit at the bottom is tmux :-) The dwarf fortress colours don't really match up well with my tmux theme... But it runs flawlessly in tmux, which really surprises me. I'll probably drag out FontForge and start making my own custom font, but this is a good start. One small strangeness is that Konsole supports ligatures and Fira Code has many of them, so sometimes the characters are displayed with the ligatures. Unfortunately, it only happens when the display code decides to render adjacent characters, so it's hit and miss. If you use a different terminal emulator, you won't have that problem (probably alacritty would work really well with this...)

Edit: I forgot to mention that there is a small bug. It doesn't seem to understand the console size right when you first start. If you resize the window, it will adjust after that.
Edit2: Playing a bit more, I just realised that Konsole is not rendering bold fonts for me (it's been like that for AGES, and I never noticed :-) ). I tried with alacritty (a new console program that I highly recommend if you don't mind getting your hands dirty -- by far the fastest rendering console app, and relatively bug free) and it works better. I'll post some new screenshots a bit later when I get a chance.
The other important thing I realised is that it is important that in your console app you turn on the setting for "use bright colors for bold", otherwise most of the characters won't render. It's a bit unfortunate that Toady is using the old standard there, but I can understand it (He probably hasn't touched that code in nearly a decade).
Finally, I've also been playing with the Inconsolata-g font, which I actually like a bit better for some characters, but it's much narrower, so everything is compressed. I'm very much tempted to make a square font now... Not that I have any time to do so :-(
