UX: Lost on next steps because of UTF-8 error

[purung]

What were you trying to do

Encrypt an .mp4 file with passphrase.
It worked with a different password so I guess the error is about the passphrase. I was not using anything that does not work in a normal password. Are there any requirements that weren't explicit?

What happened

Type passphrase (leave empty to autogenerate a secure one):
(typed a password)
Error: stream did not contain valid UTF-8

Can you tell me the following:

• Operating system
• Keyboard layout
• Terminal application
• Whether what you typed included any non-Latin characters
