DISCUSSION: down the rabbit hole of unicode characters in passwords

[Michael]

@overheadhunter once posted this image and from my point it describes exactly why having complex passwords does not gain security as much as adding length to a password will do

Password Strength

And he also did some math on the effort of bruteforcing a cryptomator vault.

I'm a future author and have some questions

You have to assume, that attackers are economically reasonable. This holds true for both, the digital and the real world. If a bank vault is known to contain $100, no sane robber would even attempt to get into it, since his expenses for planning the robbery would exceed the loot. So the real question is: How much is access to your data worth to the adversary? So you should choose your defensive means appropriately to make it economically unfeasible to attack you. I have done the calculations i…

So from my point of view it would be the much easier and safer way to create a long passwords based for example on a sentence than trying to use Unicode character in the password to make it more complex.
In addition to the user experience issue you are describing, there’s also a technical one. Despite that cryptomator does allow Unicode chars, what if you want to access your vault with third party tools, like cyberduck (or any other tool that can handle cryptomator vaults). Not sure if they do also allow Unicode chars in their tool.
(The last argument is just a minor one)
