Thanks for the pointer - I will do that!

I understand that this makes perfectly sense and would also like to
understand the source for this both in CLDR as well as glibc.

No - I'm not a Swiss resident, and can't speak french - so I'm fairly
removed from fr_CH. I tried to look this up on sites of the Swiss
national bank and similar institutions but had no luck in my research.
To the extend that I could get information from Swiss people it seemed
to be conflicting and unclear whether it related to fr_CH in particular.

So no - I wouldn't say that I have particular experience with the locale
in question.

All the best,
