A DESCRIPTION OF THE PROBLEM :
The issue can be reproduced in CJK languages, not sure if there are more languages that can make the same error.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Take Simplified Chinese as an example:
1. Install Windows Simplified Chinese Edition;
2. In 「控制面板 -- 时钟和区域 -- 区域 -- 管理 -- 更改系统区域设置」, check the box 「Beta 版：使用 Unicode UTF-8 提供全球语言支持」and restart the PC;
3. Run the code below in cmd via `chcp 65001 & java -Dfile.encoding=UTF-8 Main`;
4. Run the code below in cmd via `chcp 936 & java -Dfile.encoding=GBK Main`;

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The garbled characters should be 「系统找不到指定的路径。」 or "The system cannot find the path specified."

ACTUAL -
Both results are all:
