How to make it work when "!" is part of the password for the user being added to Filevault

Hi, thank you so much for creating this!

I've found that it doesn't work in our environment because the password for the user that needs to be added to Filevault has a "!" in it. The script fails with an error. I know that's the reason because I tested with one computer, manually changing the password locally, and then creating the encrypted strings accordingly - and it worked.

Would you happen to know of a workaround so that this would work if there is an exclamation mark within the password string?

Thanks!

The issue names no files, tests, or entry points. Reproduce the script's failure with a password containing `!` and compare it with the reported working case; the issue is complete when such a password is handled successfully.
