In clone_items, a valid name is not always created if the name of the original item is missing (None)

[sverkerEsriSE]

Describe the bug
When using the clone_items method on items that don't have the name property set, the method clone() in arcgis_impl\common_clone.py will try to create a name from the item url. In some cases this can contain Swedish characters (å, ä, ö).

The regex used only replace non word characters, but these swedish characters are word characters, but still invalid in the name of ArcGIS items.

# Code excerpt from line 2929
if name is None:
  name = os.path.basename(os.path.dirname(original_item["url"]))
  # replace non-alphanumeric characters with underscore
  name = re.sub("\W+", "_", name)  # <---- This is the problematic regex
  name = self._get_unique_name(self.target, name)
  service_definition["name"] = name

To Reproduce
Steps to reproduce the behavior:

from arcgis.gis import GIS
source_gis = GIS(profile="admin@source_gis")
target_gis = GIS(profile="admin@target_gis")

# get an item that doesn't have the .name property set, but has Swedish characters in url
item_without_name = source_gis.content.get("xxxxxxx")
new_itm = target_gis.content.clone_items([item_without_name])

error:

@sverkerEsriSE how are you creating these items with no name property set? Or is there an example of a publicly available service with swedish characters in the name that I can test?
