I'm using **TCPDFs writeHTML to convert some html-code into a pdf**. This works fine so far except that the checkmark `(&#x2713)` is converted into a questionmark instead of... well, a checkmark ;-) The PDF is created as **UTF-8,** but neither feeding the checkmark itself nor the **hex-representation resulted** in showing the correct checkmark. I tried to used the fonts **Helvetica and Times**, shipped with TCPDF, but both only display ?. Any idea how to get the checkmark into the PDF?
