Changer le modifier le format d'Encodage des fichiers csv importés dans un dataflow avec power query

Thanks I changed the format to utf-8. I also wanted to know if it is possible to automatically convert files imported into the datahouse through code written in notebook or other to avoid modifying the source files individually.🙏

Not really. Once you misinterpreted the encoding the likelihood of data loss increases, and the likelihood of being able to recover decreases.  When you see your question mark diamond it's already too late.

Do it right from the beginning.
