I was trying to rename a file with VBA, but when I put the "/" character in the name, things don't work. Then I read that I should enable "Beta: User unicode UTF-8" so that it could support the character. However, when enabling and restarting the computer, Excel says it has corrupted the file, the worksheet is saved but all VBA codes are removed. I have a backup of the file but every time I try to open it I am asked to recover and then the VBA is removed.
