To utilize one of our conversion programs I add a HEADER to a .TXT file that had Encoding = ANSI. I use a PowerShell script to add the header to the file and rename it. The script to add the header is removing the BOM so the program can't determine the encoding assigned to the file. The result is that the program corrupts special characters so the text of LÉVIS is converted to LÉVIS

Is there any way in VisualCron to do a File - Save As so I can change the Encoding assignment?

Use the Write file task. You can choose encoding there. You can write your header in vc also, and skip the powershell step
