Hello,

I am trying resolve an encoding problem using mutate gsub.

There are some words that display with error:

 ![image](https://us1.discourse-cdn.com/elastic/original/3X/5/b/5b944fdb9e3607cb1872e6e70d9fecbd1b098fa4.png)

For instance Confirma\u00e7\u00eo, correct is Confirmacao. Then a used the following gsub:

mutate {  
gsub =\> ["message","\u00e7\u00e0","cao"]}

But I still seeing error.

Can you help me?

Is there any codec to resolved it ?

I use phyton script and confirmed that encoding is unicode.

Regards

@Badger

I've resolved it using gsub. I've created one file with many parsing like:

gsub =\> ["subject", "\\u00c3", "À"]

Don't resolve 100%, but resolved my problem about ineligible text.

Thank you.
