This is just using new Intl.DateTimeFormat('ar', { weekday: 'narrow' }).format(new Date())

Even if it is just Intl doing it, I feel like vuetify should give me something to be able to fix it. It might even be some convention that is just never used in Arabic, but it seems to not be widely used.

I would really enjoy the ability to override this for specific languages, either by handing my own Intl.DateTimeFormat in, or by just having the option to use translation keys to override it.

Pretty sure Arabic is not the only language where what is defined isn't widely used.

createVuetify.date has a formats option but it isn't being used for getWeekdays, or you can pass a complete adapter. Maybe date-fns handles this differently?

If you think cldr is wrong here feel free to open an issue with unicode: https://github.com/unicode-org/cldr/blob/main/CONTRIBUTING.md
