Currently the font has no standard fallback outline in case your browser can’t display color fonts. September 2014 only Mozilla Firefox (all platforms!) and Microsoft Internet Explorer (on Windows 8.1) can display color fonts, but I’m sure Chrome, Safari and others will follow soon.
A very nice way to show the benefits of color fonts. The font is still under construction (the Dutch flag is missing).
Here is an experimental font project with a few flags.
This is screen shot of the WOFF test in Firefox 32.
If anyone wants to create their own font, this may give them a start. It needs some work. I designed the flag glyphs on the x-height.
On second thoughts, the Font File is probably more useful than the project file, then users of FontCreator 7.5 can also open it. Flags Regular.otf (34.3 KB)
