Today I discovered Gnu Unifont. It’s a really cool unicode bitmap font, with a high level of unicode coverage. There was no WOFF version available so I made one using fontforge. The version of fontforge in debian stable doesn’t have WOFF support so it was a build from source job, it’s worth noting that you need libpng-dev and libz-dev installed for WOFF support to be compiled in (otherwise it’s greyed out in the “generate fonts” menu).
You can download my WOFF here. And see it in action:
However, it only seems to work in Safari… which is a shame.
