QGIS3: OGR processing of scratch layers leads to wrong encoding

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?

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