Try this:

from_characters   = 
'\xc0\xc1\xc2\xc3\xc4\xc5\xc6\xc7\xc8\xc9\xca\xcb\xcc\xcd\xce\xcf\xd0\xd1\xd2\xd3\xd4\xd5\xd6\xd8\xd9\xda\xdb\xdc\xdd\xe0\xe1\xe2\xe3\xe4\xe5\xe6\xec\xed\xee\xef\xf0\xf1\xf2\xf3\xf4\xf5\xf6\xf8\xf9\xfa\xfb\xfc\xfd\xff\xe7\xe8\xe9\xea\xeb'
to_characters     = 
'AAAAAAACEEEEIIIIDNOOOOOOUUUUYaaaaaaaiiiionoooooouuuuyyceeee'
translation_table = string.maketrans (from_characters, to_characters)
translated_string = string.translate (original_string, translation_table)
