    return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x8d in position 33: character maps to <undefined>

Since you are using Python 3, just add the encoding parameter to open():

corpus = open(
    r"C:\Users\Customer\Desktop\DISSERTATION\ettuthokai.txt", encoding="utf-8"
).read()
