The best practice for this is to create an outline for any and all font in an SVG. Calling on the font within an SVG is not always supported depending on what program is serving the SVG data like google chrome or adobe illustrator.
To crate font outline simply select the font, click on The "Type" option in the top menu and click create outlines. Like magic your font is converted into a vector object. Note that you cannot edit the text after this because illustrator sees it as a shape. I hope this helps!
