title: 'utf-8' decode error when loading a word2vec module
body: <p>I have to use a word2vec module containing tons of Chinese characters. The module was trained by my coworkers using Java and is saved as a bin file. </p>
  
  <p>I installed <a href="https://radimrehurek.com/gensim/models/word2vec.html" rel="nofollow">gensim</a> and tries to load the module, but following error occurred: </p>
  
  <pre><code>In [1]: import gensim  
  
  In [2]: model = gensim.models.Word2Vec.load_word2vec_format('/data5/momo-projects/user_interest_classification/code/word2vec/vectors_groups_1105.bin', binary=True)
  
  UnicodeDecodeError: 'utf-8' codec can't decode bytes in position 96-97: unexpected end of data
  </code></pre>
  
  <p>I tried to load the module both in python 2.7 and 3.5, failed in the same way. So how can I load the module in gensim? Thanks.</p>
