Hi everyone i downloaded the korean fasttext model from FastText Korean Model and tried to export it to spacy using this code:

#!/usr/bin/env python
# coding: utf8
from __future__ import unicode_literals
import plac
import numpy

import spacy
from spacy.language import Language


@plac.annotations()
def main():
    nlp = spacy.blank('ko')
    with open("ko.vec", 'rb') as file_:
        header = file_.readline()
        nr_row, nr_dim = header.split()
        nlp.vocab.reset_vectors(width=int(nr_dim))
        count = 0
        for line in file_:
            count += 1
            line = line.rstrip().decode("utf-8")
            pieces = line.rsplit(' ', int(nr_dim))
            word = pieces[0]
            print("{} - {}".format(count, word))
            vector = numpy.asarray([float(v) for v in pieces[1:]], dtype='f')
            nlp.vocab.set_vector(word, vector)  # add the vectors to the vocab
    nlp.to_disk("/models/new_nlp/")


if __name__ == '__main__':
    plac.call(main)

this code i got from this answered question on stackoverflow: Export FastText from fasttext to spacy

But after executing the code i got this error at the end:

Traceback (most recent call last):
  File "C:\Users\User\fasttexttospacy\fasttexttospacy.py", line 31, in <module>
    plac.call(main)
  File "C:\Users\User\anaconda3\envs\fasttexttospacy\lib\site-packages\plac_core.py", line 436, in call
    cmd, result = parser.consume(arglist)
  File "C:\Users\User\anaconda3\envs\fasttexttospacy\lib\site-packages\plac_core.py", line 287, in consume
    return cmd, self.func(*(args + varargs + extraopts), **kwargs)
  File "C:\Users\User\fasttexttospacy\fasttexttospacy.py", line 21, in main
    line = line.rstrip().decode("utf-8")
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xed in position 0: invalid continuation byte

I don't really understand where the problem is, can somebody explain me why i get this error please? It's not clear to me.
