The problem was with the non-UTF-8-safe way that a question name
was being constructed from the question text.
I have done a proper fix with methods in the base class to
carefully construct a question name that is reasonable, and
which will fit in the database column. Then I have changed all
importers to use the new methods.
I also remembered not to break the lesson in the process.
Using consants to refer to plugin names is crazy. The whole point of
plugins is that you can install more, hence the list of constants will
never be complete.
