代小程序开发，调用上传代码接口，ext_json参数中有导航栏配置（tabBar），传进去的中文显示到小程序的时候就是两个问好，请问作何转码？

ext_json是这样的:{"color":"#999999","companyId":536,"list":[{"iconPath":"https://www.baidu.com/20190717/949665cf6b144810950e197399f390c1.png","pageName":"首页","pagePath":"pages/index","selectedIconPath":"https://www.baidu.com/20190717/e504ec5fe0f9420d8bb98431f4d91c89.png","text":"首页"},{"iconPath":"https://www.baidu.com/20190717/b0d192bc8a4e43cfbcd9fbc441f5f63d.png","pageName":"我的","pagePath":"pages/mine","selectedIconPath":"https://www.baidu.com/20190717/5869343c4a2b4cb3bfcdfce221443f54.jpeg","text":"我的"}],"projectId":653,"selectedColor":"#E840C4"}

其中list中text是显示到底部导航栏的中文，效果如下：

看底部导航栏的那几问好
