@softboy You can achieve this using IFieldMergingCallback and DocumentBuilder.InsertHtml method. For example see the following code:

Document doc = new Document(@"C:\Temp\in.docx");

doc.MailMerge.FieldMergingCallback = new InsertHtmlFieldMergingCallback();
doc.MailMerge.Execute(new string[] { "htmlField"}, new string[] { "this is <sup>superscript</sup> and this is <sub>subscript</sub>" });

doc.Save(@"C:\Temp\out.docx");

private class InsertHtmlFieldMergingCallback : IFieldMergingCallback
{
    public void FieldMerging(FieldMergingArgs args)
    {
        if (args.FieldName.Equals("htmlField"))
        {
            DocumentBuilder builder = new DocumentBuilder(args.Document);
            builder.MoveToField(args.Field, true);
            builder.InsertHtml((string)args.FieldValue);
            args.FieldValue = null;
        }
    }

    public void ImageFieldMerging(ImageFieldMergingArgs args)
    {
        // Do nothing
    }
}
