Description

I've created a point on a scratch layer and set this UTF-8 string to a text field: 

Γαζέες καὶ μυρτιὲς δὲν θὰ βρῶ πιὰ στὸ χρυσαφὶ ξέφωτο
. That's greek for 
No more shall I see acacias or myrtles in the golden clearing
.

After processing and loading the result, the text turned to 

Ga??e? ?a? µ??t??? d?? ?? ß?? p?? st? ???saf? ??f?t?

As you can see in processing logs, the fileEncoding is wrong, since it is set to "System". Maybe it's better to use UTF-8:

{'OUTPUT': <QgsProcessingOutputLayerDefinition {'sink':C:/Users/test/AppData/Local/Temp/processing_b3eeb99e5a0c4e5f990f7c7b7d49a8d6/b637937656184ec4bffdd7608cce306a/OUTPUT.shp, 'createOptions': {'fileEncoding': 'System'}}>}

Does this also affects 2.18.13?

#2 Updated by Tobias Wendorff about 7 years ago

Can't tell you. Seems like QGIS2 can't process scratch layers with OGR at all:
