Explanation
The invoice number may contain only letters (A–Z, a–z), digits and the characters + - _ /: no spaces, no full stops, no accented letters or other special characters. The requirement comes from the French e-invoicing rules, not from EN 16931.
How to fix
Ask the seller for a corrected invoice whose number uses only these characters.
