something is wrong with html escaping

[ignis32]

Code:

import xmltodict

test_xml="""<?xml version="1.0" encoding="utf-8"?>
<a> afafafa &#8211; </a> 
"""
print(test_xml)
print (xmltodict.unparse( xmltodict.parse(test_xml) ))
 

Output:

<?xml version="1.0" encoding="utf-8"?>
<a> afafafa &#8211; </a>

<?xml version="1.0" encoding="utf-8"?>
<a>afafafa –</a>

Basically, html-encoded en-dash is unescaped when parsed, but is not escaped when unparsed, generating different result then expected. (Expectations were that output of unparse would be the same as original test_xml string)

P.S. Thank you for the lib, I found it very handy for my needs.
