Upload of geopackage data made of multiple layers fails

[pchevali]

I am using the plugin with geonode 4.3.

When a geopackage made of multiple layers is uploaded its qgis name is made of an utf-8 character between the filename and the layer name : \u2014.

This result in the following error when uplaoding the layer ( from celery worker):

'latin-1' codec can't encode character '\u2014' in position 28: Body ('—') is not valid Latin-1. Use body.encode('utf-8') if you want to send it encoded in UTF-8.

The upload silently fails, as the upload is correct but the style is not visible
