How do I embed Google Web Fonts into an SVG?


Question

I'm writing an article on my site about the advantages of new web technologies, among others HTML5, CSS3 and SVGs, one of the advantages of the latter being the ability to select text in what is otherwise effectively an image.

I'm new to SVGs, and just made my first decent graphic in Illustrator. I've embedded it into a page with the GWF script for the Ubuntu font in the tag. As it turns out, the Ubuntu font displays correctly in regular text, but for this trick to work in the SVG, the Google script has to be embedded in the SVG itself. How can I do this?

Accepted Answer

You embed fonts in CSS by using base64 encoding. You can apply styles in SVG documents similar to CSS by using a <style /> element. So if you have a WOFF font, you'd embed it like this:

<style>
@font-face {
    font-family: "Sample font";
    src: url("data:application/font-woff;charset=utf-8;base64,...");
}
</style>

Where ... is the base64 encoded font data.

You can find examples of this by looking at Typekit's stylesheets. I'm not sure if the mime type of font/woff is correct, as I've also seen people claim that it should be application/font-woff. Though font/woff, font/truetype, font/opentype, etc. seem to be more popular.

Alternatively, you could actually take the SVG version of the web font and embed the SVG font's description markup inside of your document (though browser support is still very limited as Luke notes in the comments).

However, you should also be able to link to an external font according to the SVG specification. That would seem to be the best solution if you're gonna have multiple SVG documents referencing that font.
