Using Google Fonts with SVG <object>

I'm embedding SVGs in my page with the <object> tag, and they're supposed to utilize Google Fonts (e.g. Roboto). However, the SVGs aren't picking these fonts up and instead default to system fonts.

What am I doing wrong? Does every SVG require that the font itself be embedded in <style>?

Example code:

<head>
    <link href='https://fonts.googleapis.com/css?family=Roboto:400,100,100italic,300,300italic,400italic,500,500italic,700,700italic,900,900italic' rel='stylesheet' type='text/css'>
</head>

<body>
    <object width="250" height="200" type="image/svg+xml" data="img/popup_image.svg"></object>
</body>

SVG snippet:

<text font-size="14" fill="#333" font-family="Roboto">Words go here</text>

Some suggestions if you want to make your logo portable and available offline you should consume and embed the smallest version of your font possible.

First, optimize the font size, by only pulling in the stroke weights and characters you actually need.

So instead of this:

<pre><code><a href="https://fonts.googleapis.com/css?family=Roboto:400,100,100italic,300,300italic,400italic,500,500italic,700,700italic,900,900italic">https://fonts.googleapis.com/css?family=Roboto:400,100,100italic,300,300italic,400italic,500,500italic,700,700italic,900,900italic</a></code></pre>

Condense the options and also add the ?text=abc param to only grab a subset of glyphs like this:

<pre><code><a href="https://fonts.googleapis.com/css?family=Roboto:700&text=Words%20go%20here">https://fonts.googleapis.com/css?family=Roboto:700<i><b>&text=Words%20go%20here</b></i></a></code></pre>

Inside your svg, you can include a @font-face declaration in a stylesheet in the <defs> tag like this:

<pre><code><defs> <style> @font-face { font-family: "Sample font"; src: url("data:application/font-woff;charset=utf-8;base64,<b><i><b64></i></b>") format("woff2"); } </style> </defs></code></pre>

Grab the file by navigating to the google fonts stylesheet and downloading the actual .woff2 file. You can convert it to a b64 string using base64-encoder or read more at Converting and rendering web fonts to base64. Take that string and include it in your file. Just for clarity, you could also specify the unicode range on the font-face to make explicit that you're only pulling in some characters
