There are so many wonderful unicode symbols. This is amazing.
But they are all useless if I can't know if my user's font support them.
How can I find that out?
Can I track whether a user's font support a unicode symbol?
Any ways to have some kind of fallback? (If this unicode symbol isn't supported then show this other unicode symbol.)
Are there any OS/browser support references out there? (I've already extensively searched for such reference without any luck so far.)
What's your strategy to decide whether to use a unicode symbol?
I would love to use more of these lovely unicode symbols.
===Edit===
For example: I want to use the unicode "U+2605 ★ BLACK STAR" in my project's description at https://github.com/reframejs/reframe. How can I know whether this unicode symbol will correctly be displayed?
