我把自己电脑上的MC存档（windows），复制放进 fabric-server-mc.26.1.2的world 目录之中(也是windows运行)，可以正常启动，但是日志中出现乱码，能否解决呢？ 日志 如下：[20:28:21] [Server thread/WARN]: While this makes the game possible to play without internet access, it also opens up the ability for hackers to connect with any username they choose.
[20:28:21] [Server thread/WARN]: To change this, set “online-mode” to “true” in the server.properties file.

解决办法

启动前切换 CMD 为 UTF-8（推荐）

@echo off
chcp 65001

java -Xmx4G -jar fabric-server-mc.26.1.2.jar nogui

pause

这样启动就会显示成

[20:28:22] [Server thread/INFO]: Saving chunks for level 'ServerLevel[新的世界]'/minecraft:overworld
[20:28:22] [Server thread/INFO]: Saving chunks for level 'ServerLevel[新的世界]'/minecraft:the_nether
[20:28:22] [Server thread/INFO]: Saving chunks for level 'ServerLevel[新的世界]'/minecraft:the_end

至此就解决问题了。

level-name=world 目录名也为world，world目录中放的是我之前创建的存档文档，之前存档目录是新的世界，这种情况还能修改吗？

修改 level.dat 内部名称（彻底）

需要用 NBT 编辑器。
