text: Title: Is there a better way to handle big data?
  Body: I have recently downloaded a big data file and was processing it. I successfully extracted required data and stored it in a .db file. I then proceeded to convert data from the .db file to a Yaml file. But I keep on getting errors when trying to train the bot.
  
  
  ```

  ```
  
  The 1st set of errors was that the data started with a symbol. But I avoided that by removing each line containing such. Now I am not really sure what to do with errors 
  >'bool' object has no attribute 'strip'
  
  and
  >unacceptable character #x007f: special characters are not allowed
  
  Any help on how to solve this or any advice to handle big data would be very much appreciated.
