Consider adding charset=utf-8 to CSS and SVG files?

Based on https://sonarwhal.com/scanner/82d0ae4e-aa8d-4b9b-9d32-24c1b0817136, we don't.

CSS inherits from the document, so this isn't really necessary except if people navigate to the CSS file directly.

For SVG I can't find a specification anywhere.

Maybe we should do JS, text, etc. while we're at it?

SVG would follow XML, no? So that would default to UTF-8. When you navigate to CSS or JavaScript directly it should also default to UTF-8 in theory, but browsers don't really do it that way.

But doing it for all of them is probably still a good idea so user agents can avoid going down more complicated code paths.
