I’m not quite sure which symbol you tracked down, but ∋, (code number 8715) is the more correct character to use.
It is the opposite of the symbol you listed and is read “contains.”
i.e.
Some Site ∋ A page
(read “some site contains a page”)
There’s also ∍ (8717), which is a smaller version of the same glyph.
And technically, the element symbol is not quite the same as an epsilon. According to the Unicode standard, a lower case epsilon is ε (949). My math professor actually writes epsilon this way to be sure it isn’t confused with the element symbol. However, some people do write epsilon the same as an element symbol.
vkaryl – you probably never learned this because you never studied Greek. It’s not a common school class. I only know because my Latin teacher was a Greek major, so when she didn’t feel like teaching Latin one day, she taught us the Greek alphabet.
