Table tools - csv export encoding

Hi Allan,
I'm using datatables for a long time and it saves me a lot of time !

I've a question about table tools csv export :
Is there a way to export data in latin1 in order to open correctly the file in Excel (2003) ?
I tried this piece of code without the expecting result :

{
	"sExtends": "csv",
	"sButtonText": "",
	"sToolTip": "Exporter au format csv",
	"sTitle": "Mon titre",
	"sFieldSeperator": ";",
	"sCharSet": "latin1",
        "mColumns": [ 0, 1, 2 ]
}

I think the answer is in "sCharset" parameter, but I tried "iso88591", "latin1" and I open this file in Excel with bad encoding...

I would be great if you had a solution or a track !

I'm using tabletools 2.1.5 dev

Thank you,
Joseph
