How to know a site's charset?

How to use ASP to inspect a site's head meta charset?

example
charset=ISO-8859-1
charset=UTF-8
charset=EUC
charset=ISO
and so on


Thanks

 

Do you mean using asp to detect other website's charset?

 

Yes, please help.

 

Using xmlhttp
getting the html source from the url you want to check.
Using regex to check if there has the charset meta and fetch the value of it.
