Solution 1:[1]

You can add NSCharacterEncodingDocumentAttribute:@(NSUTF8StringEncoding) options: 

NSDictionary *options = @{NSDocumentTypeDocumentAttribute:NSHTMLTextDocumentType, NSCharacterEncodingDocumentAttribute:@(NSUTF8StringEncoding)};

Hope it will work.

Solution 2:[2]

Swift Version:

let options: [NSAttributedString.DocumentReadingOptionKey: Any] = [
    .documentType: NSAttributedString.DocumentType.html,
    .characterEncoding: String.Encoding.utf8.rawValue
]
