I don't see it either, but I do see all the fi's becoming fi ligatures. The CSS is specifically enabling it with the line: font-feature-settings:"liga", "dlig", "onum"; (and its vendor variants) liga is standard ligatures, dlig is the "discretionary" ligatures (less standard ones like ct), and onum is old-style numerals. EDIT: Ligatures sure are weird in monospace though. I'd personally disable it for code samples... http://www.microsoft.com/typography/otspec/featurelist.htm http://www.microsoft.com/typography/otspec/featurelist.htm http://blog.fontdeck.com/post/15777165734/opentype-1 http://blog.fontdeck.com/post/15777165734/opentype-1 https://developer.mozilla.org/en-US/docs/Web/CSS/font-feature-settings https://developer.mozilla.org/en-US/docs/Web/CSS/font-featur...
