I what encoding?

Obviously, you cannot use "ISO-2022-JP".
If you can handle "UTF-8", then use "unicode('\u2013').encode('utf-8')".

You can also use the "xmlcharref" error parameter for your
"encode(iso-2022-hp)". In this case, your character would 
become an XML character reference. They have the form
"–". Browsers usually are able to display them.
