For my terminals, I use MingLiU, on OS X. It's primarily an Asian scripts font, and the roman characters are monospaced.

There's little difference between O and 0 or l and 1, though, so I don't use it for coding, but it's good enough for my use of the terminal.

Luxi Mono isn't bad either, but the capital o and the zero are almost pixel for pixel identical, which is a deal breaker for me. https://www.fontsquirrel.com/fonts/Luxi-Mono
