编码自适应：自动识别并强制切换为 UTF-8

Windows 中文系统默认控制台编码是 GBK（CP936），脚本中的中文会乱码

切换到 UTF-8（CP65001）后，无论原系统是 GBK 还是 UTF-8 均能正确显示

# ----- 记录原始代码页（脚本结束时恢复，避免影响后续命令）-----
$cpOutput = & chcp.com 2>$null
if ($cpOutput -match ‘\d+’) {
$script:OriginalCodePage = ($cpOutput -replace ‘[^\d]’, ‘’)
}

# ----- 强制切换到 UTF-8 -----

# 即使编码切换失败也不中断（某些受限环境会失败，但脚本主体功能依然可用）
