Can you do animated textures for unicode chatcters?

Using minecraft 1.21.1 I have a server I am using luck perms on and I have fonts that have custom texture applied to them

works great

I am trying to apply a mcmeta file to animate the texture, I have done this before on blocks and items and it works fine, but I can't for the life of me get the unicode to animate, just shows me the entire file. Is it even possible to animate the unicodes?
