Note that Source Code Pro does not have an Italic typeface yet. Italics are commonly used for source code comments and most editors will automatically emulate the shapes, often with poor results. Active development is currently being done in this direction .
So the time needed is probably shorter than the time spent on the regular variant, but only by a small factor, certainly not orders of magnitude.
It's a combination of Inconsolata for Latin characters and an IPA font variant called Migu 1M for Japanese characters in the same dimensions.
I've never seen it as a binary, so you have to run a script to build it yourself.
I'm using a fairly old version of emacs without Xft2 support so use codec with it.

Note there's an S in Cosmic :)
In my terminal:

Here an example of Sublime Text 3 + Ubuntu Mono 10pt + Blackboard Theme: http://imgur.com/qW8yyi0
Edit: OK, I found the character/theme you are using, but what version of Ubuntu Mono do you have? It won't handle that for me :/
Edit 2: I found a Powerline patched version, but that doesn't seem to work either… Maybe I will just switch back to Consolas
I've recently switched to Fira Mono , designed by the awesome Erik Spiekermann for Mozilla.
Otherwise I think it was Monaco way before those.
BUT when using low-dpi monitors, very few get the hinting right, and bitmap (6x13 ) is king.
I would humbly suggest trying either MonteCarlo  or its derivative, Tamsyn . Certain characters (like the "@" symbol) look much better in either of these fonts.
I use it in Sublime Text and also for my Terminal Monokai theme: https://github.com/Pephers/monokai-for-terminal-app
Thanks for the suggestion anyway.
Meslo. Can't get enough of it.
It is worth noting that all quality programming publications display code in fixed pitch. Knuth, in his epochal "Art of Computer Programming", uses fixed-pitch serif for source code. Petzold's "Programming Windows" uses fixed-pitch, as does Kernighan & Ritchie's "The C Programming Language".
But in the code itself, this isn't a consideration.
For example, cli mysql wouldn't be too much fun in Geneva. There's a nice visual hint between labels and data in lines of whois output, and that hint would be icky in a proportional typeface:
owner: NETLINE PERU
And, although it's not very common, I occasionally use it as a typo-checker. If I have a function or a class where I can't easily abstract out some kind of repetition, then using a monospaced font with variables that are the same number of characters lets me visually see right away if I've mistyped something. I couldn't quickly find an example, but it was the first programming-specific monospace font thing that came to mind.
Not left edges. Even in non-monospace fonts, every blank is the same with, same with every tab.
