```
"Bloqué par le filtrage par réputation" : {
            "type" : "text",
            "fields" : {
              "keyword" : {
                "type" : "keyword",
                "ignore_above" : 256
              }
            }
          },
          "Date de début" : {
            "type" : "text",
            "fields" : {
              "keyword" : {
                "type" : "keyword",
                "ignore_above" : 256
              }
            }
          },

```

Thanks for answers ! 🙂

You need to reindex and make sure you are using UTF8 as for character encoding.

The problem is that it's the CSV that I'm importing that produces these weird characters ... And I can not change the export encoding of my CSV ☹

I did not mean exporting to CSV but how did you import the CSV file into elasticsearch?

sorry I had misread,

using logstash and filebeat:

- I put filebeat listening on the directory where I send my CSV.
- I get input {beats =\> "5044" } in my logstash pipeline

I think you need to configure an input Codec: [https://www.elastic.co/guide/en/logstash/6.2/plugins-codecs-line.html](https://www.elastic.co/guide/en/logstash/6.2/plugins-codecs-line.html)

And define the right `charset`.

I moved the question to #logstash as I feel it's where everything should be solved.
