character-encoding

I'm developing a firefox plugin and i fetch web pages to do some analysis for the user. The problem is when i try to get (XMLHttpRequest) pages that are not utf-8 encoded the string i see is messed up. For example hebrew pages with windows-1125 or Chinese pages with gb2312.

I already tried the following:

var uDecoder=Components.classes["@mozilla.org/intl/scriptableunicodeconverter"].getService(Components.interfaces.nsIScriptableUnicodeConverter);
uDecoder.charset="windows-1255";
alert( xhr.responseText );

var decoder=Components.classes["@mozilla.org/intl/utf8converterservice;1"].getService(Components.interfaces.nsIUTF8ConverterService);

alert(decoder.convertStringToUTF8(xhr.responseText,"WINDOWS-1255",true));

I also tried escape/unescape/encodeURIComponent

any ideas???

How can I tell if a CSV is in UTF-7 or UTF-8

Excel seems to save CSV files in (what I think is) UTF-7, despite the fact that most information I have read suggest that in general, you should not UTF-7. Indeed, other applications (Text pad, which lets me choose) save things in UTF-8 (or Unicode etc, but UTF-7 is not even an option). Using .NET… >>> More
