[gdal-dev] UTF-8 problem with MSSQLSpatial and ogr2ogr
Hello, I am trying to load a shape file encoded in UTF-8 in SQLServer2008. I use this command from ogr2ogr to load the data's: ogr2ogr --debug on -f MSSQLSpatial "MSSQL:server=localhost;database=ogr2ogrTest;Trusted_Connection=True;" "myShapeFile.shp" -t_srs EPSG:4326 -dsco ENCODING=UTF-8 -lco ENCODING=UTF-8 -overwrite -progress When I check the records in the DB, some fields are not correctly encoded. According to SQLServer documentation and to my understanding: in order to store unicode, the fields must be declared as NCHAR or NVARCHAR and the insert or update statements must append 'N' before the value (INSERT INTO tForeignLanguage ([Name]) VALUES (N'Араб')) I also search about unicode in this list and found: - http://osgeo-org.1560.n6.nabble.com/RFC-23-OGR-Unicode-td3759338.html - http://trac.osgeo.org/gdal/wiki/rfc23_ogr_unicode I downloaded the latest source code from http://www.gdal.org/daily/ and check into mssqlspatial component and found that the driver does not respect these assumptions: - fields are created as VARCHAR, - statements does not append 'N' I really need this unicode support but I am not very familiar with C++, could you help me to implement a patch to test the loading of a shapefile into SQLServer2008. What classes should I change and how? Thank you for your help. Best regards.

Hi All I am a newbie of GDAL. I want to convert a shape file to GeoJSON file. I have downloaded GDAL 19 (MSVC 2010 win64) binaries. However, when I try to convert to GeoJSON. It says "Failed to create geoJSON datasource" I am using the following code ogr2ogr -f "geoJSAON CENO.json CENOVUS.shp Please tell me where I am wrong.

You should make sure to request with buf_type = gdalconst.GDT_Int16. Then iterating the buffer with getShort() should deliver the expected values. Otherwise use the version of ReadRaster() that accepts a short[]. That will be simpler to use.

Re: [gdal-dev] fail to build gdal 1.9 with minGW
I think I get it more clearly. It 's a linking problem now. When I
compiled GDAL 1.9 linked statically with proj. I got the error
'undefined reference to 'pj_init' '. The libray 'libproj.a' must be set
in my project. But I use same configure script to test my GDAL 1.6. It
turns out that I just need to set ' libgdal.a' without ' libproj.a' .
How can I make the linking way of GDAL 1.9 just like 1.6 ?

Thanks for your reply. I have tried 'make clean' and then rebuild GDAL.
And I have also modified GNUmakefile ,replaed '${GDAL_ROOTs}' for '.'
and then 'make clean' and rebuild it again. Unfortunately, I failed
again. I use command ' ./configure --prefix=. ' Should I need to add
option '--host=mingw32' or '--without-libtool'?
I have not a mingw environment to test. Is it a compilation problem or a linking
problem ?
