react/jsx-pascal-case incorrectly flags $ as not being in pascal case

[Haegin]

I have a component named $ and the react/jsx-pascal-case rule is saying that it's not in pascal case. As $ is a symbol and not upper or lowercase letter, this shouldn't be an error.

What's the component's full name?

[Haegin]

@ljharb it's just $. We use it for formatting currency values.

<$>{price}</$>

Fascinating. I certainly think a standalone character of any kind should be permitted by the rule; so maybe just "bail out if the component name has 1 code point"?
