C＃：如何將特殊字符寫入ADLDS？

Question

我正在嘗試將聯繫人寫入ADLDS ldap，以便將它們用作Yealink T48G的電話簿。有時，聯繫人的名字包含一些特殊字符，如「ö」，「ß」和「é」。如果這些字符包含在「givenName」或「displayName」字段中，那麼電話和ldap客戶端都不能正確顯示它們，而是顯示其他一些字符（例如「ö」 - >「ö」），但「名稱「和」dn「字段正確顯示這些字符。

如果我通過ADSI-Edit或任何其他工具插入聯繫人值，手機會正確顯示名稱，但我的應用程序不再能夠從givenName讀取插入的特殊字符並顯示一些questionmark-boxes，但是dn並且名稱字段被正確讀取。

我已經嘗試過使用utf-8，utf-16，utf-32，iso-8859-1和windows-1252作爲我的應用程序的編碼。

所以問題是我如何使用C＃在ADLDS實例中的inetOrgPerson的givenName屬性中存儲這些特殊字符？

這個問題是通過設置應該使用的protocolversion解決Ť o版本3.

connection = new LdapConnection(new LdapDirectoryIdentifier(host, port)); 
connection.SessionOptions.ProtocolVersion = 3;
