Non-ASCII in server console causes a panic

[Max Schorr]

Starting a server with boxes, and the output containing a character outside of ASCII causes Boxes to panic with the following error:

thread 'main' panicked at src\minecraft\server.rs:91:33:
called `Result::unwrap()` on an `Err` value: Error { kind: InvalidData, message: "stream did not contain valid UTF-8" }

Steps to reproduce:

1. Create a server with boxes server generate or boxes create
2. Install a plugin that logs a non-ASCII character (for example, Multiverse-Core prints § when warning about a deprecated event.)
3. Start the server with boxes start <server>
4. Boxes panics due to the non-ASCII character
