How to resolve "UnicodeDecodeError: 'utf8' codec can't decode byte 0xff in position 566: invalid start byte"

[Yahsaswi]

I have some large text files which have such characters and i wish to ignore such characters and proceede with the sentToVec conversion .. I see the below error , please help me fix this .
File "kfold1.py", line 34, in
model = Sent2Vec(LineSentence(sent_file), model_file=input_file + '.model')
File "/Users/ypochampally/Documents/RESEARCH/workspace_latest/Wiki_Actors/src/om_TextClassification/word2vec.py", line 800, in init
self.reset_sent_vec(sentences)
File "/Users/ypochampally/Documents/RESEARCH/workspace_latest/Wiki_Actors/src/om_TextClassification/word2vec.py", line 809, in reset_sent_vec
for sent in sentences:

yield utils.to_unicode(line).split()

return unicode(text, encoding, errors=errors)

I get the same error when I try to load the model using,
model = Word2Vec.load_word2vec_format('test.txt.model', binary=True)
