datepicker fr-ch localization file is wrong (de-ch is correct)

datepicker fr-ch localization file is wrong (de-ch is correct)

File was not edited in UTF-8, so on display localized text presents rubbish instead of accent characters. I had to copy inside content of fr localization file to make it work correctly.

Also, I don't understand why the reference to swiss-french in file name and content is fr-CH, instead of fr-ch (idem for de-ch)?
