Failed to decode ndjson new format with python

Hi @cjcenizal

Been working on it yesterday - I actually found out at least on my problems

Can't really figure out what happened but in few visualizations it appears that I had "­­­­­­­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­ ­" in a custom label. (it doesn't seem to be spaces in a row but another character ...)

Well, once the export done, the custom label looks like that :

{
  \"enabled\":true,
  \"id\":\"6\",
  \"params\":{
    \"customLabel\":\"­­­­­­­­ ­  ­  ­  ­  ­  ­  ­  ­  ­  ­  ­  ­\",
    \"field\":\"YYYY_MM\",
    \"missingBucket\":false,
    \"missingBucketLabel\":\"Missing\",
    \"order\":\"desc\",
    \"orderBy\":\"1\",
    \"otherBucket\":false,
    \"otherBucketLabel\":\"Other\",
    \"row\":false,
    \"size\":12
  },
  \"schema\":\"split\",
  \"type\":\"terms\"
}

Which seems to be converted by spaces too by the browser but it actually looks like :

on my NotePad

and like :

on my output console

Would you have any idea of what is this ?
