It is easy to import such values into fields of type "text" by surrounding them by quotation marks, but it does not work for fields of type "char", all characters after a comma are lost.

I simply want to import product attribute values containing commas.

*** Update ***

he behaviour is strange enough: I was able to import the exact same value correctly into the field Value in the model product.attribute.value before without any problems (and without any quotes). The values are stored properly in the attribute values table. It only happens, when I try to import these values into the product templates.

Import into Attribute Values (working properly):

The field odooattribute_id is the External ID of the attribute.

This is how I want to import the corresponding values into the product templates (which works flawlessy, when the attribute values do not contain commas):

The external ID here is the External ID of the corresponding Product Template.

And this is the result:

The value to be imported gets truncated after the comma and therefore the corresponding value could not be found.

Meanwhile I did report an issue on Github: https://github.com/odoo/odoo/issues/27569

Any ideas/hints are very appreciated.
