New submission from William D. Colburn:

This seems to be just like issue6010, which is closed as "not as bug" which is 
simple irresponsible on the part of Python.

The problem is that I can store data into sqlite3 which cannot be retrieved.  
The data I encountered was a string with a \xa0 in it that was read from 
urllib2.  I deposited that data into an sqlite3 database with no trouble at 
all.  Later, however, sqlite3 would throw an exception when I tried to retrieve 
the data.

Martin v. Löwis says this is user error because sqlite3 assumes UTF-8. It makes 
no sense that storeable data cannot be retrieved and that the failure of 
sqlite3 is a user-error.  If sqlite3 assumes UTF-8, then the error should have 
been caught when I did the store because I was not storing UTF-8 data.  
Accepting bad input and blaming the user later down the line is bad bug 
handling, especially because the two events might be separated by a tremendous 
gap of time and code which makes debugging quite hard.  I was only able to find 
the errant character by popping the streamed webpage into emacs as both python 
and firefox showed me a normal looking string with nothing wrong with it.
