I have tested the export from svg to emf (in windows) using the GUI and I noticed a checkbox for exporting the texts as paths. This checkbox is by default checked, so as I didn't want that configuration I have unchecked it and the export worked like a charm.

When I tried the same from command line by typing 

inkscape svgBasicChart.svg --export-emf=svgBasicChart.emf

the export performed had the texts exported as paths, but I didn't find any option to avoid that from command line as I found in the GUI.

Is this option available in any way for command line?

Thanks in advance
