[MC-157942] Unable to start server with UTF-8 on Windows

An error occurs when the following command is executed at Windows Command Prompt.

Commands

chcp 65001
java -Dfile.encoding=UTF-8 -Dsun.err.encoding=UTF-8 -jar server.jar nogui

Log output

This issue is not serious for most people, but I decided to report because of server quality.

Workaround

Specify the following command line argument when starting the server:

-Dsun.stdout.encoding=UTF-8

Confirmed for 1.19.2

There is currently no way to set the server's stdout encoding. Which means certain characters are printed as ? in the log file. The console window however does correctly display this.

Example text: "这种情况是油泵故障灯，检查一下油泵插头是否接虚，然后查一下油泵内管道压力是否符合正常值。"

Actually the workaround now is `-Dfile.encoding=UTF8` to set the console stdout correctly. However, utf8 should probably be default to allow logging foreign characters.
