need a function to know if a dashicon exists.

[sebastienserre]

Hello,

Is there a way to know if a dashicon exist or not?

I think there's currently no function and I don't really know if this is possible to create it or not...

In my mind, it would be a function as <code>is_dashicon_exists( 'dashicons-linkedin')</code> returning true or false.

Do you think it should be possible to create?

Add a kind of proof of concept

As per a discussion with @clorith on Slack #core, I had the idea on a private project where I use the Dashicons.
I made a foreach to display social network and fall on <span class="dashicons dashicons-linkedin"></span> which doesn't exist yet.
SO I searched how to know programatically is the dashicon exists or not

Hi @sebastienserre about 70 new dashicons might appear in WP5.5
Your function is a very nice idea, but you cannot create your own array as it is depending on the WP version that is running.
Please note ​https://make.wordpress.org/design/2020/04/20/next-steps-for-dashicons/ that dashicons is going out of life, but it will of course still be around for a while. Let's maybe have a chat together?
