[Qgis-developer] QGIS 2.10.1 Pisa - Read CSV file problem

[DelazJ]

Hi,
I think this should be reported. If there is no reason why a csv should not
have column fields name as numbers, then this is a bug, maybe a small bug,
but it's a feature that QGIS needs to handle.

The CSV files are from South Africa's 2011 Census - as put out by StatsSA,

why a csv should not have column fields named as numbers (shapefiles does
accept this kind of field name so joining csv like this might be allowed),
then this is a bug (or feature request?), maybe a small bug for some of us.
We don't all have same skills, what appears easy to handle for someone can
be a huge barrier for someone else. And as a community, we should make easy
the path for every one.
I know there are priorities but reporting an issue doesn't mean that it
should be fixed in the day. In QGIS Hub, you'll easily find reports that
are there for years. IMO, it's a feature that QGIS needs to handle. Report
it and if one day, someone finds enough time and skills to fix it, it'll be
done.
