Just to provide an example of what MvL already said:

py> line = u"Delta=\u0394"
py> f = open("data.txt","w")
py> f.write(line.encode("utf8"))
py> f.close()
py> print repr(open("data.txt").read())
'Delta=\xce\x94'

py> import codecs
py> f = codecs.open("data2.txt","w","utf8")
py> f.write(line)
py> f.close()
py> print repr(open("data2.txt").read())
'Delta=\xce\x94'
