Missing some basic Unicode glyphs

[onpon4]

Describe the bug
I was just doing some testing with using this font on a game I'm developing and noticed some missing glyphs. I don't see an existing issue for missing Unicode glyphs so I figured I'll start a new one. I noticed in the game that the following glyphs seem to be missing:

• Ellipse (…)
• Non-breaking space ( )

So I did some checking on dafont.com (I couldn't find a better convenient way to check what glyphs are and aren't available) and saw that at least the version of the font they have is also missing the following glyphs:

• En dash (–)
• Em dash (—)

I noticed that some others are missing as well (like the arrow symbols and music symbols), but I figured I'd specifically note the ones above since they are necessary components of proper English text (and probably text of other languages as well).
