Great tool. I've been doing some tests with Emoji / SVG favicons. There's a couple of problems. They don't show up on some old browsers and in google search results. For old browsers there's a solution, which is to have a raster .ico version of the icon at the root of the domain: e.g. example.com/favicon.ico But for the google issue, I'm not sure if that's the solution. Whatever google is using to render svg icons in their search results just doesn't like emojis. I haven't tested that yet. also as others have pointed out there's this bit of code that can save you an http request: <link rel="icon" href="data:image/svg+xml,<svg xmlns='http://www.w3.org/2000/svg http://www.w3.org/2000/svg' viewBox='0 0 99 99'><text y='.9em' font-size='90'>EMOJI</text></svg>">
