Fixing DXF import encoding problem using PyQGIS3

Question

I have text with French accent in a DXF I import in QGIS3.16. The DXF is encoded in UTF-8 but as a result, the features attributes have encoding problems. The é charcacter are written é. Here's a portion of the code used:

# -*- coding: utf-8 -*-
layer = QgsVectorLayer(dxf_path + "|layername=entities|geometrytype=Point", "dxf_linestring", "ogr")
layer.setProviderEncoding(u'UTF-8')
QgsProject.instance().addMapLayer(layer)

When I convert the DXF from UTF-8 to ANSI in Notepad++, the problem is solved but I would prefer to convert in the script rather than converting the whole file.

Answer 1

Maybe I didn't find a working method because the DXF dataprovider has not the capability.

Instead, I used a file encoding convert trick:

with open(file_utf8, 'rb') as source_file:
  with open(file_latin1, 'w+b') as dest_file:
    contents = source_file.read()
    dest_file.write(contents.decode('utf-8').encode('latin1'))

And it worked perfectly for my plugin.
