What happened?

I cannot confirm this on any other OS other than Windows 10 and Windows 11.

When trying to sign in to a self-hosted server protected by a self-signed certificate, you are prompted to provide the CA certificate to validate the server.
If the certificate is named, OR resides in a folder on the OS containing a character not present in the English alphabet (ø å æ õ for example) then the certificate cannot be imported and login fails.

Opening the developer tools shows a pair of traces as follows:

File name containing a European character:

Server Log: Warning: Ignoring extra certs from `C:\hello\internalæ.crt`, load failed: 
error:02000002:system library:OPENSSL_internal:No such file or directory

Folder name containing a European character:

Server Log: Warning: Ignoring extra certs from `C:\hellõ\internal.crt`, load failed:
error:02000003:system library:OPENSSL_internal:No such process

  }
}

Moving the certificate to another folder and ensuring the filename doesn't contain these characters works as expected.

How can we reproduce the issue?

Attempt to import a self-signed certificate containing å, ø, æ, õ, ã, or similar character from outside of the US alphabet.
