Is there an Icon for SIGMA?

Flow

I tried fontawesome to get a SIGMA icon and it seems that Vaadin does not have the pro icons from FontAwesome?? I need to add the SIGMA icon to my tree component .

Where can I get it? and if not in FontAwsome where else can I look?

Thanks

Just use a unicode character (Σ, σ) - no need for an icon.
