Big update 7/10/2012; all Latin Extended-B characters are here now. Fitting them into a width of at most 6 pixels was challenging, and it shows on a few of the more ridiculous glyphs (Do we really need DZ as one glyph? Maybe the monospacing justifies it, though the widest glyphs still have no gap between them and the next one.). I am fairly proud of the curls on some of these though. Feel free to clone and see for yourself!

And here's a sample with some of the new glyphs.

Here's a revised sample just to show off Polish and Vietnamese language support. Same photo, same credit as before. UPDATE: Hooks over Vietnamese letters now look less like grave accents.

Hooray, a Top Pick! I've been using Mandrill more often this year than during 2012 (when I worked on it), and I have noticed that I have really gotten used to some of the properties of the font. If you only use ASCII, it pretty much has a higher line-height and some squashed lower-case letters ('s' is a little weird, but I don't notice it in prose anymore). The nice thing is that most of the other Latin-something glyphs blend smoothly with the ASCII; Icelandic users might appreciate having a narrow monospaced font with an æ that is still legible at size 12, I think most Eastern European languages can use this, and Vietnamese... well it looks really good at size 24/32 (depending on the program), and the hook above diacritic looks like the logical not sign '¬' at size 12/16. Still, I am fairly sure that a Vietnamese-proficient reader with sharp enough vision and a screen that doesn't shrink pixels (Retina displays might be good or bad at this) could adapt to the 2-3-pixel difference between 'ỏ' and 'ó', but I need to confirm this with someone who can read the language. I learned a lot working on Mandrill, and I hope someone finds it useful -- for Vietnamese, Swedish, Croatian or English!
