API Netbox or pynetbox: how to pass accented characters without triggering Pynetbox.RequestError?

Question

I try to send data from a French database to Netbox but spaces and accented characters trigger an error as in the example:

Post_dept = nb.dcim.sites.create([
     {
    "name":"Saône et Loire",
    "slug":"saône et loire",,
     }
)   
Pynetbox.RequestError :
[{"slug":["Enter a valid \"slug\" consisting of letters, numbers, underscores or hyphens."]}]

I have developed this function which goes through a dictionary list and converts each problematic character into a compatible format. But the function is heavy and the renaming of value is confusing. How to encode the fields to keep the original format and be compatible with the API?

Thanks!
