How to rename an index with a special char (tabulation) in its name?

[tbarnier (Thierry Barnier)]

A colleague created an index through an API

Name of the index: LF_IDX_THE_INDX

But - no idea how - with a leading TAB char in front

When running
GET _cat/indices?v

the LF_IDX_THE_INDXshows a "whitespace" in the listing

But when running

GET *LF_IDX_THE_INDX/_settings

Shows

{
  "\tLF_IDX_THE_INDX" : {
    "settings" : {
      "index" : {
        "creation_date" : "1573809743739",
        "number_of_shards" : "5",
        "number_of_replicas" : "1",
        "uuid" : "WKBJDi-bTl2FWYi0IHATCg",
        "version" : {
          "created" : "6050499"
        },
        "provided_name" : "\tLF_IDX_THE_INDX"
      }
    }
  }
}

With a magnificient '\t' in the 'leader' position.

Is there a way to escape this shar to rename, create an alias or whatever?

Thanks in advance

I didn't think indices could even have upper case characters in the names, strange.

Maybe you can use the url encoding for tab, like:

POST /_aliases
{
    "actions" : [
        { "add" : { "index" : "%09LF_IDX_THE_INDX", "alias" : "alias1" } }
    ]
}
