Xamarin 在运行时形成删除空格答案

【问题标题】：Xamarin forms removing whitespaces in run-timeXamarin 在运行时形成删除空格
【发布时间】：2018-09-08 12:28:54
【问题描述】：

我们正在 Visual Studio 中使用 xamarin 表单构建一个跨平台应用程序，对于 iOS，该应用程序运行良好，但是当我构建它并在我的手机甚至模拟器上运行时，空格或只是空格是从我的字符串中删除，使用静态资源或只是 xaml 文件中的字符串本身，编码是 utf-8 并且我确实检查了 strings.resx 都是 xml:space="preserve" 我已经检查了我能想到的一切，如果有人能在这方面启发我

例如隐私政策字符串中的空格，当在 android 上运行时，它会删除空格...即使将字符串放在资源或 xaml 页面上也没关系

谢谢

编辑：遵循部分代码

xaml 页面前

【问题讨论】：

这个太含糊了，可能贴一下对应的组件，e.g.资源代码、xaml 页面等
@Csharpest 我的错，添加了一些代码
只是一些想法：问题是否仅出现在 FontSize="Micro" 上？也许您在 Android 上为您的标签自定义渲染器会导致问题？
@user2074945 不，即使使用默认的“欢迎使用 xamarin 表单”内容页面，它仍然会删除空格

标签： c# android xamarin.forms cross-platform

【解决方案1】：

对于任何感兴趣的人，我发现了问题

这是一个使用 Iconon 和 FontAwesome 创建的图标文件，它强制删除空格，删除文件修复了所有内容
