Я использую этот код для преобразования html -текстовой строки в attributeString. 

if let description = article.description {
    let data = Data(description.utf8)
    if let attributedString = try? NSMutableAttributedString(data: data, options: [.documentType: NSAttributedString.DocumentType.html], documentAttributes: nil) {
        attributedString.addAttributes([NSAttributedString.Key.font: UIFont.systemFont(ofSize: 18), NSAttributedString.Key.foregroundColor: UIColor.subtitleColor], range: NSRange(location: 0, length: attributedString.length))
        articleView.contentTextView.attributedText = attributedString
     }
}

и странные символы, выходящие , как здесь . Как их удалить?
