I have been looking at some open source fonts for font embedding with @font-face lately. A good place to for good OFL licenced fonts is The League of Movable Type
To be able to test their excellent fonts and how they behave in different browsers I’ve built a little Specimen Browser using Tim Brown’s fantastic Web Font Specimen and some lines of JavaScript.
Just open up the Web Font Specimen Browser in the browser you want to test in and select a font from the drop-down. Without a selection it will default to Georgia and you can test all system fonts too by adding a ‘font’ parameter to the URL like http://marctobiaskunisch.com/WebFontSpecimenBrowser/?font=arial
This is work in progress and my plan is to add more fonts from other sources as well.
Here’s the link to the Web Font Specimen Browser again.
