Before digging deeper into the issue, I wanted to ask here if there are any implicit assumptions about string identity and interning throughout the interpreter implementation. For instance, are two single-char strings having the same content supposed to be identical objects?
I think this is not a bug if the code relies on the fact that an empty string is a singleton. This obviously is an immutable object and there is no public method to create different empty string.
Really?
x = u'\xe9'.encode('ascii', 'ignore') x == '', x is '' (True, False)
