title: Can only concatenate str (not "bytes") to str [TypeError]
body: <p>I am not too knowledgable in Python however i have imported an old project from github and trying to fix it but am getting this last error when trying to load a model asset. I'm sure its hiding in plain sight. The line number it refers to is: string += byte</p>
  <pre><code>def ReadNullTerminatedString(f):
      byte = f.read(1)
      string = &quot;&quot;
      while struct.unpack('B', byte)[0] != 0:
          string += byte
          byte = f.read(1)
  
      return string
  </code></pre>
