}
htmlparser.Parse(sr);
pdfDoc.Close();
byte[] bytes = memoryStream.ToArray();
memoryStream.Close();
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();

Try setting the encoding as well as the font face:

StyleSheet styles = new StyleSheet();
styles.LoadTagStyle("body", "face", "Arial Unicode MS");
styles.LoadTagStyle("body", "encoding", BaseFont.IDENTITY_H);
Also, the ParseToList method returns a List<IElement>; there’s no need to convert it to an array:

var elements = HTMLWorker.ParseToList(sr, styles);
foreach (IElement element in elements)

I suspect you don’t need the htmlparser.Parse(sr); line, since you’ve already parsed the content with the ParseToList call.
