Check each country's language rules for consumer contracts

How to do it

The Consumer Rights Directive leaves language to each country. Article 6(7) lets Member States keep or add language rules for contract information, so the answer differs by country. Keep one list of the countries you sell to, the rule in each, and its source. A safe default is to give the terms, the order confirmation and the cancellation form in the language of the shop the customer used. Keep the order button wording in each language, as Say on the order button that the order costs money says.

Examples

JavaScript example

const missingRules = CHECKOUT_COUNTRIES.filter(country => !CONTRACT_LANGUAGE_RULES[country]?.source);
if (missingRules.length) throw new Error(`No recorded language rule for ${missingRules.join(', ')}`);

Python example

missing_rules = [country for country in CHECKOUT_COUNTRIES if not CONTRACT_LANGUAGE_RULES.get(country, {}).get("source")]
assert not missing_rules, f"No recorded language rule for {missing_rules}"

How to check

The country list has an entry with a source for every country in the checkout's country list. A test places an order in each shop language and finds the terms and confirmation in that language.
