UnicodeDecodeError migrating to 5.2

Ok, I've installed the new 5.2 release and found a bit of a problem with migration (no python 3 yet).

During this migration Step:

plone/plone.app.upgrade/blob/master/plone/app/upgrade/v52/final.py#L74


                behaviors.append(behavior)
                logger.info(
                    '"{dotted}" has no name registered. '
                    'kept it dotted.'.format(
                        dotted=behavior,
                    ),
                )
        fti.behaviors = tuple(behaviors)
        logger.info(
            'Converted dotted behaviors of {ct} to named behaviors.'.format(
                ct=fti.title,
            ),
        )


    logger.info('Done moving dotted to named behaviors.')




KEYS_TO_CHANGE = [
    "plone.always_show_selector",
    "plone.authenticated_users_only",
    "plone.available_languages",

If any of your type's title has special characters (e.g. Seleção), migration will fail with UnicodeDecodeError.
My solution was to leave the title without special characters in order to finish the migration.

So I guess this post is just an FYI if someone ran into the same problem.
