title: Instead of color, symbols apears in aws cloudwatch console with winston
body: <p>I am using winston for logging as below.</p>
  
  <pre><code>const winston = require('winston');
  const {transports, format, createLogger  } = winston;
  const { combine,errors, splat,timestamp } = format;
  
  const logger = createLogger({
      level:  process.env.LOG_LEVEL,
      transports: [
          new transports.Console({
              format: combine(
                  timestamp({
                      format: 'YYYY-MM-DD HH:mm:ss'
                  }),
                  errors({stack: true}),
                  splat(),
                  winston.format.colorize(),
                  format.json()
              )
          })
      ]
  });
  
  module.exports = {logger};
  </code></pre>

  "message": "apiKeyId: ef12dv3n3b", 
  "level": "\u001b[34mdebug\u001b[39m",
  "timestamp": "2019-08-20 07:07:16" 
  }
