whitespaces in ids cannot be reimported

[jackahl]

I am in a Plone 4 -> 6 migration and the source site contains a lot of objects that have blanks in there ids (no idea, if that is usually possible in Plone 4). In the export file they are encoded as %20. E.g. "@id": "https://mysite.com/my%20object".

When reimporting in 6 I run into:

Traceback (innermost last):
  Module ZPublisher.WSGIPublisher, line 181, in transaction_pubevents
  Module ZPublisher.WSGIPublisher, line 391, in publish_module
  Module ZPublisher.WSGIPublisher, line 285, in publish

  Module plone.dexterity.content, line 776, in manage_delObjects
  Module plone.folder.ordered, line 68, in _getOb
AttributeError: 'my%20object'

could it be a good idea to replace the whitespaces with "-" on export?

Who creates content-ids with whitespaces? I would keep that in my global_dict_hook but you can create a PR with a fix. Keep in mind that @id and id of the parent would need to be updated as well. And maybe old links that do not use resolveuid would break...
