‘ “ é == ‘ “ é, but on what encoding/reference?

Question

I have a ColdFusion script that does:

<cfset content = replace(content,"&##147;","""","all")>

Which replaces &147; by ". Google understands this too, if you type ‘ “ é at its search box its transformed on the results page to ‘ “ é".

If I search for é on this HTML Entity Character Lookup page, it'll return é to me. But ‘ and “ doesn't return 145 and 147.

So the question is, what's the numeric reference, character encoding, or whatever else, is being used here by ColdFusion? Where can I see that 145 maps to ‘, 147 maps to “ and 233 maps to é?

Bonus thanks if someone provides a page listing these characters (since more are replaced on the script).

Edit: Havenard made me realize I was typing the wrong characters because my browser (Opera) was displaying them badly, so now I'm using Firefox to edit this question, and hopefully it'll be clear :)

Cheers,
