[xsde-users] Error during serialization of the character 'ü'

[Thomas Frenzel (TomSun)]

Hi Boris,

i created a xml schema which describes logging data. One log entry has a message, time stamp, log level ... etc.

When i try to log a message with the character 'ü' i get an xml_schema::serializer_exception with the text "illegal UTF-8 character" and what "xml error"

The create the message string like that:

LOG_ERROR("An error occured during the call of the method '%s'.ü",lastMethodName);

the lastmethod name will be inserted in the message string using the vsprintf_s function. Afterwar When i remove the last character (the 'ü'), i don't get the exception.

Code:
  messageLength = _vscprintf( messagePattern, messageArguments ) + 1; // terminating '\0'
  message = new char[messageLength];
  printResult = vsprintf_s( message,messageLength, messagePattern, messageArguments); 
  message[messageLength-1] = 0;
  LogEntryData* logEntry = new LogEntryData();
  logEntry->Message(message);

And this is my common serialization code:
      XmlWriter writer(xmlStream);
      this->m_serializer.pre (*data);
      writer.write(encodingInfo,strlen(encodingInfo));
      this->m_documentSerializer->serialize (writer, xml_schema::document_simpl::pretty_print);   
      this->m_serializer.post ();

Encoding info is the following string:
    this->encodingInfo = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n";


My Project is build with the UNICODE preprocessor command.

What i am doing wrong? Like i said, just removing the ü from the message helps. But normaly this should not be a problem in an UTF-8 world.

Thanks in advance,
Tom
