I have a web service that submits forms to a workflow. When I submit a form from the browser, Chinese characters entered into text boxes or rich text boxes are passed to the service as question marks. The service exposes two methods: one that takes the form as an XML string and another that takes it as an XML document. The problem occurs with both.The problem does not occur when submitting a form from the InfoPath application; nor does it occur if I use the browser to manually create and save a form to the SharePoint library. Any help would be much appreciated.
