How to create ews soap request with Chinese character in it? RRS feed

  • Question

  • I want to send creating calendar item operation request using EWS, and some of my content, for instance, Subject, may content Chinese characters. Here is what my request soap looks like

    <?xml version="1.0" encoding="utf-8"?>
    <Envelope xmlns="">
      <RequestServerVersion xmlns="" Version="Exchange2007_SP1"/>
      <CreateItem xmlns="" SendMeetingInvitations="SendToNone">
          <DistinguishedFolderId xmlns="" Id="calendar"/>
          <CalendarItem xmlns="">

    I encode this xml with utf-8 and send it to my testing exchange server, and after a while, it displayed on that server, but with question mark in Subject property instead of '新建日程'. All other properties are displayed correctly.

    So I wonder where I did wrong that the Chinese content can not be displayed correctly. Any suggestions?
