[QGIS-Developer] QGIS and QLocale handling not used?

[Andreas Neumann]

Hi, 

It is really a mess. F.e. in Switzerland some cantons use the comma,
some the decimal point (officially). On the federal level they use the
comma - I guess this is what Switzerlands official positions is: use the
comma as decimal separator. BUT: in practice most people I know use the
point as a decimal separator. See also
https://en.wikipedia.org/wiki/Decimal_mark 

What a mess. Probably we are the only country listed in both sections:
comma and the point (depending on the province). I don't know who had
this brilliant idea that some provinces would use the one and some the
other. 

If someone works on locale changes, I would propose that there would be
a separate setting where people can choose if they want the point or the
comma as a decimal separator. 

Thanks and greetings, 

Andreas

I tried to clear up some of these issues during the Nodebo hackfest,
but:

1. coming from a locale which uses the NORMAL "." as decimal
separator, I have no idea what the expected/proper behavior should be
for locales which use ","

2. no-one I asked from these locales could even give me a definitive
answer about what the correct behavior is

So I quickly decided to let someone else handle this mess ;)
