GIS-Lab community has worked on this and here is our results.
We develop a patch which add two methods GetEncoding and SetEncoding.
At this time only GetEncoding for shapefiles is realised. With this
methods programmer can get encoding programmatically. Patch
uploaded to the bugtracker: http://trac.osgeo.org/gdal/ticket/882
How this works: first we try to read DBF LDID and get encoding from
here (even CPG file is available), if LDID is 0 or 87 (system encoding)
driver will try to read encoding from CPG file.
Encoding in CPG file can be written according to the DBF LanguageID
standard or according to the codepages ANSI, OEM etc. GetEncoding
method will handle all this variants automatically.
We'd appreciate if someone could have a look and sign off or comment on the
