it's at least explicitly mentioned in the docs to create your database with a latin1 character set:


Engine=InnoDB CHARACTER SET 'latin1';

It's most of the time not a good idea to alter defaults if you do not now the internal working of
the software very well, as can be seen in this example.

It's up to debate if this is a bug of the software or if the documentation should be more urgent about setting up
the database schema. The current wording is:

"Example: configuring MySQL"

This contains some ambiguity (an example is, most of the time, not the only way to do something).
But the rest of the wording is imho relatively clear, that you should not configure the database with a different schema.
