How can that happen if the programmer (or a module she has imported)
isn't messing with the locale?  If the programmer is messing with the
locale, really they need to be careful.  A magic codec whose encoding
changes *within* a process is an accident waiting to happen.

Do you have a real use case for the "'locale' codec's encoding changes
with the locale within process" feature?
