Pros
Pro Unicode support
This font covers the entire BMP and work is still being done to expand it even further.
Pro Plain enough
The font does not distract you with weird glyphs – but is interesting enough to be loved.
Pro Legible
The font is wide enough to be legible but not too much so you can actually fit some information on your screen.
Cons
Con The zero character is not sufficiently distinguished from the capital "O" character
Especially for programming, zero characters should have slashes to make them distinct from other circular or oval characters.
Con Missing weights
The regular weight is a little bit light for me, I'm waiting for the medium weight.
