我们有一个客户，其中对Exchange Web服务的多个GetItem SOAP调用返回包含以下内容的XML：
<t:MeetingTimeZone TimeZoneName="��������������������������������">
（32个空字符）。随后，我的XML.XmlDoc.LoadXMLData调用在该行上引发了“无效的Unicode字符”EDOMParseError - 当然。
服务器版本为：
<h:ServerVersionInfo MajorVersion="15" MinorVersion="1" MajorBuildNumber="361" MinorBuildNumber="14" Version="V2015_10_05" xmlns:h="http://schemas.microsoft.com/exchange/services/2006/types" xmlns="http://schemas.microsoft.com/exchange/services/2006/types" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
这是在线Exchange365。
这里可以发生什么？这个奇怪的TimeZoneName如何蔓延？可以预防吗？
我现在唯一能推荐的是他们重新创建这些约会并检查问题是否消失，或过滤掉�的XML会降低速度。
FWIW，这是返回的完整XML：
