Meta's charset is rendered as camel case

[dpostolachi]

When I use react-dom's renderToString the meta property charset is rendered with camel case like this:
<meta charSet="UTF-8"/>
insted of
<meta charset="UTF-8"/>

I'm using react and react-dom of version 16.2.0

Hey @Voodoo-Child. This is currently expected behavior. See #10863 and #11492 (comment) for some context on this decision.

I hope that helps, thanks!
