Hello, We're using a socket connection to send information between a C++/C#-environment on one side to a Python/PythonDotNet environment on the other side. The information is packed in an XML string format. Packing and unpacking is done using the same C++/C#-code on both sides, thanks to PythonDotNet. When sending an XML string containing another XML string, any occurrences of " will cause the reminder of the string to be cut off. Replace any " with ? and the entire string is received. The curious thing is, this only happens when sending from C++/C# to the Python side. Sending the string the other way does not produce the same symptom. Ideas, anyone? Can the translation from a DotNet string to a Python string make this happen? Regards, Torleif
