Group separator migration from U+00A0 to U+202F

So I've to confess that I did focus on French and only applied for fr-FR, but 
there was a lot of work, see http://cldr.unicode.org/index/downloads/cldr-34#TOC-Growth
waiting for very few vetters. Nevertheless I also cared for English (see various tickets), 
and also posted on CLDR-users in a belated P.S. that fr-CA hadn’t caught up the group 
separator correction yet:

Also I’m sorry for failing to provide appropriate feedback after beta release and to post 
upstream messages urging to make sure all locales using space for group separator be 
kept in synchrony.

I’m posting here with respect to people not monitoring CLDR-users Mail List. where this 
post is expanded. For further details and CLDR ticket link, please look up:
