The problem is that QLocale does not allow to only format numbers: you get
all from a locale (date, currency etc.) or none, which is not currently a
big problem because we only format dates and numbers (AFAIK), but using
QLocale::setDefault at the application level seems to me the right solution
for the long term.

I'm afraid that the last one requires changes through all the code and the
implementation of custom validators and custom widgets, so I believe it's a
no go, unless we wanted to go back to UI inconsistencies where some widgets
use system locale (scale and coordinates to cite some) and some other don't
and get back to a certain number of bugs that this implementation fixed.


I'm working on my proposed solution, let's see if that suit all needs (I
think it should: at least you should have the "old" behavior with dot and
no group separator without the old inconsistencies).


Btw, there is already a workaround: change your number formatting options
at the operating system level and QGIS will respect your choices.
