Description of problem:

The number formatting in the folllowing locales is wrong in respect of 
thousands
grouping - the sign used is a whitespace, but it should be a "'".

de_CH
de_CH.iso88591
de_CH.utf8
fr_CH
fr_CH.iso88591
fr_CH.utf8
it_CH
it_CH.iso88591
it_CH.utf8


How reproducible:

Always

Steps to Reproduce:

1. Assign a locale, like with setlocale (LC_ALL, 'de_CH'); in PHP
2. Output a number with at least 4 digits left of the decimal delimiter
  
Actual results:

1 234 567 890.00

Expected results:

1'234'567'890.00



In the end, it_CH,de_CH and fr_CH should be the same for the formatting.

So in summary it should be somthing like this:

Numeric definitions
                Decimal point char: '.'
                Thousands separator: '''
        Monetary definitions
                International currency symbol: CHF
                Local currency symbol: Fr.
                Decimal point char: '.'
                Thousands separator: '''
                Symbol for positive monetary values: ''
                Symbol for negative monetary values: '-'
                Fractional digits for international formatting: 2
                Fractional digits for local formatting: 2
