The Umoⁿhoⁿ

I've been telling the kids that all I know about Native Americans are the Nebraska ones I learned about in school, but then I read about the Umoⁿhoⁿ.

"Who are they," I wondered.

I think it's just an improved spelling of "Omaha".

It's actually kind of cool-looking, with the superscripts. I suggest that everyone switch over to this spelling.

But how to pronounce it?
