[LucileDT]

Reduced Test Case

Reduced test case

(not sure if it works as I build my sources using Webpack and I have to use a different method on jsfiddle).

Bug Description

Scenario:

• create a calendar (v5.10)
• use "fr" as locale
• use week: 'long' in a date format function (titleFormat, slotLabelFormat, ...)

Expected behavior:

The text generated is "Semaine [week number]"

Current behavior:

The text generated is "Week [week number]"

Screenshots

Here a screenshot with successively week: 'long', week: 'short', week: 'narrow' and weekday: 'narrow', day: '2-digit'.

It hasn't been translated yet, would need to add weekTextLong to https://github.com/fullcalendar/fullcalendar/blob/master/packages/core/src/locales/fr.ts
