Swift UTF8 encoding and non UTF8 character

Question

I\'ve a some text from json file. In this text I\'ve applied UTF8 encode but this encoder don\'t recognize a non standard character àèìòù and it\'s capital char

Answer 1

I've found a solution.

The UTF8 take 8 bit of table ASCII, and the UTF16 take 16 bit ASCII table, the solution is simple by modifying my function to:

func stringToUTF16String (stringaDaConvertire stringa: String) -> String {
    let encodedData = stringa.dataUsingEncoding(NSUTF16StringEncoding)!
    let attributedOptions = [NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType]
    let attributedString = NSAttributedString(data: encodedData, options: attributedOptions, documentAttributes: nil, error: nil)!
    //println(attributedString.string)
    return attributedString.string
}
