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

[Chris Crook]

Hi Zoltan

I've removed this constraint on field names from the QGIS code - this will apply in the next release of QGIS.  So no need to raise a bug.  If you do want to (or have other issues/feature requests) information about how to do so is at http://qgis.org/en/site/getinvolved/development/index.html#bugs-features-and-issues.  Feedback from the user community is certainly encouraged.

Until the next release though you may have to write a script to deal with the files (or live with the replaced field names).

As to the silence - who knows!  Certainly this hasn't been raised to my knowledge, and the "feature" has been there a couple of years now.  I think if many users were affected this would have come up sooner, but great that you have raised it.

Cheers
Chris
