What makes you think that?  Please isolate this part of your problem 
with a simple short program, so we can diagnose it.  You're probably 
getting confused between str() and repr().  The latter adds backslash 
escape sequences for good reason, and if you don't understand it, you 
might think the strings are getting corrupted.
