Contrib-sun-position nodes: moon icon not scaleable as font

Continuing the discussion from Simple moon phase + picture for dashboard:

Just a small question on this module and its marvelous moon phase icon which apparently is a (hidden?) font character. In my text box

<font size="24px">{{msg.payload}}<font>

the icon is displayed but I cannot scale it larger on some of my browsers. Is there another way to enlarge this font character? <span> or <div> tags?

The node-red-contrib-sun-position uses the unicode symbol of the used font.

You can try to use a different font?
