How can I convert an svg-glyph into a path?

Question

I have extracted an svg-glyph like this from an svg-font:

I would like to convert it into a svg-path that I could use in a css-file. What do I need to do?

but nothing shows up, I'm not sure how I can test it.

As a reference, this one works:

   content: url("data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' width='6' height='30'><polygon fill='#00bbff' points='0,0 6,15 0,30 '/></svg>");

Answer 1

I've added a viewBox to define the visible area and removed the # by using black as the fill colour. It does now display on Firefox.
