Swift UTF8编码和非UTF8字符

Swift UTF8编码和非UTF8字符

我找到了解决方案。

UTF8采用8位表ASCII表，而UTF16采用16位ASCII表，解决方案很简单，只需将函数修改为：

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