Hello everyone,

I am trying to upload a file to a ftp, the name of this file contains an accent, the name of file is Martín.txt, i am using qlik web connectors  Qlik FTP/SFTP Connector... the file is uploading fine but the name of file in ftp change to Mart�n.txt and that is wrong....

this is my configuration in Qlik FTP/SFTP Connector 

I need that the name file in ftp will be the same Martí.txt no Mart�n.txt,  will someone know what can i do?
