title: What does [40m[32minfo[39m[22m[49m means on DotNetCore logs
body: <p>I have a DotNet Core application inside a Docker container and when I look into the logs produced by ILogger, I can see those characters:</p>
  <pre><code>[40m[32minfo[39m[22m[49m: Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker[1] 
  [40m[32minfo[39m[22m[49m: Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker[2] 
  
  </code></pre>
  <p>Can you help me understand what they mean?</p>
