You can say things like the different "styles" that exploit Unicode on a myriad of websites such as https://qaz.wtf/u/convert.cgi?text=Hello are not technically "fonts" but it's a distinction without a meaningful difference. You have script, fraktur, bold, monospace, italic...

Fraktur is interesting because it’s more a writing style, verging in a character set in its own right. However Unicode doesn’t directly support all of its ligatures and such.

None of this is in any way justification for turning Unicode into something like SVG. Even the pseudo-drawing capabilities it does have are largely for legacy reasons.
