In ColdFusion I can determine the ASCII value of character by using asc()
How do I determine the UTF-8 value of a character?

Do you mean that you have the UTF character in your editor and you want to get the UTF-8 representation of it, as inU+00A2? Have you looked atCharsetDecode()helpx.adobe.com/coldfusion/cfml-reference/coldfusion-functions/…

<cfscript>
x = "漢"; // 3 bytes
// bytes of unicode character, a.k.a. String.getBytes("UTF-8")
bytes = charsetDecode(x, "UTF-8");
writeDump(bytes); // -26-68-94
// convert the 3 bytes to Hex
hex = binaryEncode(bytes, "HEX");
writeDump(hex); // E6BCA2
// convert the Hex to Dec
dec = inputBaseN(hex, 16);
writeDump(dec); // 15121570
// asc() uses the UCS-2 representation: 漢 = Hex 6F22 = Dec 28450
asc = asc(x);
writeDump(asc); // 28450
</cfscript>
USC-2 is fixed to 2 bytes, so it cannot support all unicode characters (as there can be as much as 4 bytes per character). But what are you actually trying to achieve here?
Note: If you run this example and get more than 3 bytes returned, make sure CF picks up the file as UTF-8 (with BOM).
