As there was no reply to his mail, I assume that there is no GDAL/OGR
creation option for the LDID and it is unlikely that there will be one
in the near future.

http://resources.arcgis.com/content/kbase?fa=articleShow&d=26015 that
ESRI set the LDID to zero to indicate an unknown LDID. From my
reading of the OGR sourcecode, it seems that OGR uses the shapelib
default LDID of 0x57 (previously it was set to 0x3, or windows-1252).
Is there any way to specify this value using the OGR API, or do I need
to use shapelib directly to create my shapefiles in order to do this?
Cheers,

The .cpg files we generate through ArcGIS desktop contain the string: UTF-8
Some time ago, there was a mail on this list about problems in case of
conflicting information in the .cpg file compared to the Language Driver ID
(LDID) in the header of a dBASE file, see:

Okay, I will take that approach then. Thank you all for your help.
What specific value should I write into the .cpg? The string '65001'
or the string 'utf-8' or something else?

Hi Francis,
what does not portable mean? ArcMap handles UTF-8 fine, if the correct
encoding is written into the .cpg file. Recent shapelib should handle
this fine, too. If there is any problem with a specific GIS program, a
bug report for that GIS program might be the right thing to do.

But honestly I've found hard to find information about this. I'd be
very happy to be corrected if this is not the case!

Where did you hear this?

Hi there,
I'm trying to write data from a Microsoft Excel .xls file into a
shapefile, using OGR's Python bindings in Python 2.6. This is going
well, but I am having some problems when I try to write values that
contain so-called "smart quotes". Smart quotes are special
characters, defined as characters 0x91 through 0x94 in Windows-1252 (
see http://msdn.microsoft.com/en-au/goglobal/cc305145.aspx ).
What is the best way to save this data to a shapefile using OGR? I
need the shapefile to be interoperable with other programs, including
but not limited to ESRI products. While I assume I could simply
translate these characters to standard ASCII, I would prefer not to if
possible. I also haven't tested the shapefiles with data from other
character encodings.
I have heard that the use of UTF-8 in shapefiles is not portable. I
am also aware that shapefile.cpg can store a shapefile's codepage. I
don't know how to put these pieces together to create a portable
solution, however.
Apologies if this is a newbie question, but I can't find answers on the
web.
Thanks,
Francis Markham
