delphi html decode

I'm using Delphi 2009 and want to decode an HTML encoded string, for example:

' -> '

Thanks in advance

Look at the HTTPApp unit. HTTPDecode and HTMLDecode (as well as the Encode functions). You should find this in your Source/Win32/Internet folder.

For example: ∴ → ∴

function HtmlDecode(s: UnicodeString): UnicodeString;
{

   Known issue, it doesn't handle entities with characters code points above $FFFF (65536)
   e.g.: &
