by experience, you must first decode your string to encode it
so[color=blue][color=green][color=darkred]
>>> goodProcRef='Gr\xfc\xdf'.decode('latin-1')
>>> goodProcRef[/color][/color][/color]
u'Gr\xfc\xdf'
now you could compare goodProcRef and plist[-1].Reference and get "True"
When strings are unicode strings, then you can encode them easily
[color=blue][color=green][color=darkred]
>>> goodProcRef.encode('UTF8')[/color][/color][/color]
'Gr\xc3\xbc\xc3\x9f'[color=blue][color=green][color=darkred]
>>> plist[-1].Reference.encode('UTF8')[/color][/color][/color]
'Gr\xc3\xbc\xc3\x9f'
Hope it can help,
