来自 Azure ServiceFabric 服务的无效字符读取 xml 文件

Question

当我在我的 Azure ServiceFabric 集群的任何 Web Api 服务上添加 Swagger (v2.5) 并且 swagger 文档文件包含重音符号（á、é、í...）时，我得到此错误：

Invalid character in the given encoding

我正在将 xml 文件的 uri（路径）传递给 swagger：

services.AddSwaggerGen(options =>
{
    ...
    options.IncludeXmlComments(myxmlpath);
    ...
}

但根据 this post 我应该通过 StreamReader 来指定编码，所以我为此交换了代码：

services.AddSwaggerGen(options =>
{
    ...
    options.IncludeXmlComments(() => new XPathDocument(
                    new StreamReader(myxmlpath, Encoding.UTF8)));
    ...
}

这样我设法避免了错误，但是大摇大摆UI我看到了奇怪的字符。例如，它显示的不是 áéíóú：

��

我不明白为什么它在我的本地集群中有效，但它在我的 Azure 集群中给我带来了编码问题。我没有设法在我的本地集群中重现错误。

为什么文件解析在任何方面都取决于部署服务的节点（本地或 Azure）？

这是我在交换代码之前的整个堆栈跟踪：

终于找到问题了。这在 Azure 环境中不是问题。我在 VSTS Replace Tokens 中有一个发布步骤，在 auto 中有 Files Encoding 选项。我将其更改为 utf-8 并且有效！
