HuangJT commented on issue #6587: Can't upload CSV in Apache Superset
URL: https://github.com/apache/incubator-superset/issues/6587#issuecomment-504332365
 
 
   Had issue with the csv upload when the csv file has Chinese characters.It is fine when I replace Chinese characters with English.
   
   How to solve?
