Check the ENCODING on your file by following these steps:
- Open the file in a text editor such as "Notepad".
- Click "File" from the Menu bar, then choose "Save As"
- The encoding for the file should appear near the "Save" button
If the encoding is UTF-8, please change it to ANSI, and then save your file. Then resubmit your file through Corridor.
