You don't need to convert the data into base64. I think the SVG syntax doesn't have any "crazy" characters in it, so it's safe to use.

Set the encoding to UTF-8, and drop the <svg> in there:
```
'data:image/svg+xml;utf8,<svg ... > ... </svg>'
```

You can't use an <img> element when referencing an external CSS stylesheet from XML. You need to use an <object> element like this answer recommends, and prepend an <?xml-stylesheet?> processing instruction in order for the SVG+XML blob to be able to find the FontAwesome glyph for the HTML entity .

function addSVG() {
  var ele = document.getElementById("svg");
  var svg = `
    <?xml-stylesheet type="text/css" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css"?>
    <svg xmlns="http://www.w3.org/2000/svg" width="20" height="20">
        <text x="4" y="15" style="font-family: FontAwesome" fill="red">&#xf007;</text>
    </svg>`
  var output = `data:image/svg+xml;utf8,${svg}`

  ele.type = 'image/svg+xml';
  ele.data = output;
}
addSVG()

<head>
  <link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css" rel="stylesheet">
</head>

<body>
  What it should look like:
  <svg xmlns="http://www.w3.org/2000/svg" width="20" height="20">
    <text x="4" y="15" style="font-family: FontAwesome" fill="red">&#xf007;</text>
  </svg> What it looks like:
  <object id="svg"></object>
</body>

Why do you need it in img tag? SVG is an image! You do not need it to put in something else.

May be I do not know something from you, but I think this is just a bad idea from you.

My suggestion: put SVG in HTML with font-awesome icons directly:

Your benefit from this: all modern browsers support it without any limits like in img tags or as background image.

var divSvg = document.getElementById('svg'),
    pics =
    {
        user: {col: '00a', icon: 'f007'},
        home: {col: '08c', icon: 'f015'},
        folder: {col: '88f', icon: 'f07c'},
        gear: {col: '5a0', icon: 'f013'},
        flag: {col: '05a', icon: 'f024'},
        leaf: {col: '080', icon: 'f06c'}
    },
    svg =
'<svg xmlns="http://www.w3.org/2000/svg" width="32" height="32">\
    <text x="4" y="24" fill="COLOR" style="font:24px FontAwesome;cursor:pointer">PIC</text>\
</svg>';

for(var title in pics)
{
    var newSVG = svg.replace('PIC', '&#x'+pics[title].icon+';');
    //we put it in "B" tag to have a title because IE
    //does not support title attribute and title tag in SVG
    divSvg.innerHTML += '<b title="' + title + '">' +
                    newSVG.replace('COLOR', '#'+pics[title].col) + '</b>';
}

divSvg.onclick = function(e)
{
    if(e.target.tagName == 'text')
    {
        document.getElementById('output').innerHTML = 'Was clicked on ' +
                                // we take title from "B" tag:
                                e.target.parentNode.parentNode.title;

        /* if you need you can use:
        switch(e.target.parentNode.parentNode.title)
        {
            case 'user': alert('Here some procedure with user');
            case ...     YOUR CODE
            and so on... YOUR CODE
        }*/
    }
}

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css" rel="stylesheet">
<div id="svg"></div><br>
<div id="output">Please click on any icon.</div>
