Input Mono – A Typeface for Code, from Font Bureau
This font is beautiful and has really nice options.<p>But it lets me with a bitter feeling: as a potential user, I won't even consider using it because non-ASCII latin letters are not treated first-class: it's nice that the letter `i` has all these form variants, but they're not applied as soon as a diacritic comes into play (`ï`, `î`, etc.).<p>The same letter with and without a diacritic (eg. `e` and `é`) don't even look the same, letting the user with the feeling that this potential need has not even been considered.<p>EDIT: According to <a href="http://input.fontbureau.com/info/" rel="nofollow">http://input.fontbureau.com/info/</a> maybe I'm missing something and my criticism only applies to the online demo.
