[webkit-dev] DOMDocument outerHTML and NSStringEncoding

Hi I would like to save the outerHTML of a DOMDocument, but to do the right thing and get an NSData out of that string, I need to know what is the NSStringEncoding that should be used, which would be derived from the the charset declaration of the document, and ISOLatin1 if there are no charset declared I think. I didn't find an obvious answer looking at the documentation. Is there one ? And if not, is there a way to avoid to re create a mapping between charset declarations and NSStringEncodings ? Thanks, Benoit
