【报Bug】HBuilderX 编译时会将 theme.json 转换为 Unicode 编码，导致微信开发者工具报错

示例代码：

fix-theme：

// 修复 uni-app 编译后的 theme.json 文件
// 解决 Unicode 编码和 BOM 问题

const fs = require('fs');
const path = require('path');

// 主题配置（直接在脚本中定义，避免编码问题）
const themeConfig = {
"light": {
"navigationBarTextStyle": "black",
"navigationBarBackgroundColor": "#F8F8F8",
"backgroundColor": "#F8F8F8",
"backgroundTextStyle": "light",
"tabBarColor": "#666666",
"tabBarSelectedColor": "#2a82e4",
"tabBarBackgroundColor": "#ffffff",
"tabBarBorderStyle": "black"
},
"dark": {
"navigationBarTextStyle": "white",
"navigationBarBackgroundColor": "#1a1a1a",
"backgroundColor": "#121212",
"backgroundTextStyle": "dark",
"tabBarColor": "#888888",
"tabBarSelectedColor": "#64b5f6",
"tabBarBackgroundColor": "#1a1a1a",
"tabBarBorderStyle": "white"
}
};

// 目标文件路径
const targetTheme = path.join(__dirname, '../unpackage/dist/dev/mp-weixin/theme.json');

try {
// 检查目标目录是否存在
const targetDir = path.dirname(targetTheme);
if (!fs.existsSync(targetDir)) {
console.error('❌ 目标目录不存在，请先编译项目');
process.exit(1);
}

// 将配置转换为 JSON 字符串（无 BOM，UTF-8）
const themeContent = JSON.stringify(themeConfig, null, 2);

// 写入目标文件（确保无 BOM）
fs.writeFileSync(targetTheme, themeContent, { encoding: 'utf8', flag: 'w' });

console.log('✅ theme.json 已成功修复');
console.log('? 目标文件:', targetTheme);
console.log('? 内容预览:', themeContent.substring(0, 100) + '...');
} catch (error) {
console.error('❌ 修复失败:', error.message);
process.exit(1);
}

操作步骤：

每一次运行打包都会出现

预期结果：

正常运行和发行使用

实际结果：

微信开发工具报错：
