Given a huge shapefile which needs desolving by one attribute field to reduce redundancy. The GDAL dissolve functionality does that quite swiftly but the output attributes change the encoding so äöü become to unusable ?squares.
What i've tried so far:
- Adding a hugeshpfile.cpg that additionaly declares UTF-8: ?squares
- Doing the detour via Postgis: same result
- The native QGIS dissolve function freezes no matter if shapefile or postgis
- Doing it via SQL query in pgadmin results in a different error messages.
While trying around i didn't encounter a possibility to influence the encoding. How can that be achieved or am i missing out on some format constraints?
