You can always copy the character, paste it into an new document in BBEdit and select "Hex Dump Front Document" from the File menu.

Just for grins, here's how you can get the unicode value in hex (for that particular character on that particular page) with JavaScript in Safari 5:

str = document.getElementById("footer").children[1].children[0].innerText
"Family 사이트 ▶"
str.charCodeAt(str.length - 1).toString(16)
"25b6"
