Suppliers see the assessment form and the data inside it in one consistent language, chosen by them rather than inferred from their browser.
A supplier who has not chosen a language works in English throughout, interface and data. A supplier who picks a language from the switcher gets that language throughout.
Assessment panels offer your configured languages plus Chinese and Turkish, which are available to suppliers whether or not you have enabled them. If a language pack cannot be downloaded on a slow or restricted network, the form falls back to English completely rather than mixing two languages on one screen.
Search in the form matches composition, fibre and component names against both the active language and English, so a supplier working in Chinese can type either name and find the same entry. This works in one direction — a supplier working in English will not find an entry that exists only under a Chinese name.
