Re: [Qgis-user] Shapefile with file .cpg(codepage)

[Neumann, Andreas]

Hi, 

I wonder why this is not the default? If a .cpg file is present, one can
assume that the information is correct. Probably in some edge cases it
may be false, but in the majority I assume the .cpg files to contain
correct information.

Hi,

QGIS uses the .cpg file when you deselect the Option  "Ignore shapefile 
encoding declaration"


You find it:
Settings > Options >  Data Sources

Then there are no encoding-problems tu use QGIS with Shapefiles in in a 
mixed environment.


Cheers

Re: [Qgis-user] Shapefile with file .cpg(codepage)

[Bernd Vogelgesang]

Hi Even,

the encoding is often a source of confusion. I work in a mixed  
environment, me on Linux (so UTF-8 is the "System"-default), the rest is  
using on Windows (with Windows-1252 I assume)
Transfering shapes often results in crippled data, and I have not found  
workflows/settings that this will not happen.


Is there anything I can do about it, so we do not have to adjust things  
manually all the time, or first look if the codepage is correctly set ?


Cheers
Bernd

Andrea,

OGR does use the .cpg file when present (I'm just updating
http://gdal.org/drv_shapefile.html since it only mentions the reading of  
the
codepage byte in the DBF header, but the .cpg presence overrides that)  
and

QGIS uses OGR to read shapefiles.

But, in QGIS, the default behaviour is to make OGR *not* use the encoding
detected by the OGR shapefile driver and use instead the user defined  
encoding
in the GUI. Unless you go to Settings / Options / Data Sources and  
uncheck the
"Ignore shapefile encoding declaration", in which case OGR will manage  
the

transcoding itself.

Hi, 

QGIS is using OGR to read/write shapefiles. 

http://www.gdal.org/drv_shapefile.html does not mention the .cpg files,
so I assume, OGR does not support them. If you want to see this
addressed, I would contact the GDAL/OGR devs.

Hi,
I would say that QGIS does not use the .cpg file. But you have the possibility 
to make the correct encoding in the layer properties under "General -> Layer 
info -> Data source encoding".

[Qgis-user] Shapefile with file .cpg(codepage)

[Andrea Peri]

Hi,
I have some shapefiles with an extra file having extension .cpg.
The .cpg extension is a optional extension for declaration of Code-Page.
Is this file knowed and supported from QGIS 2.14. ?

I don't know if the qgis when loading a shapefile is using the ogr or
instead is using an own shapefile provider, but however I don't know
if gdal is knowing and using this .cpg file.
:)


Thx,
