Are there any alternatives in HTML for the entities ∩ and ∪?

I am开发者_JS百科 using the Symbol font within an Illustrator graphic. Now, I would like to use the same symbols directly in HTML. I found equivalents to phi (φ), rho (ρ), and even the check box like symbol: ✓. However, I am missing the open and close arcs from the Symbol font. They are equivalent to ∩ and ∪, but they seem wider. So...is there a better alternative to map the Symbol font entities to HTML entities?

Thanks.

Here are searches for some alternatives for

• cap
• cup and union

It looks like the n-ary ones might be good, but I'm not exactly sure what you are looking for.

Note that you can try different web fonts by mousing over over the top right corner where it says "Font?"

I wrote this tool to help discover these, so I hope it helps you out.

You mean something like this?

∩ 
∪

You can find it easy, just use search

or choose the block:

Html code can be found there as well.
