[gdal-dev] Encoding when creating pdf

[Jorge Gustavo Rocha]

Hi Aneta,

I didn't try on the command line. But I've tried with QGIS (QGIS uses
GDAl to generate PDFs).

I was able to create a PDF with accent characters everywhere. Check the
attached PDF.

I've used a layer name with accents; I've used a label with accents.
I've also used as attribute field name with accents and the value with
accents. The label is displayed properly on the feature.

I'm using GDAL 3.3.0dev, compiled with --with-poppler. I would recommend
a more recent version of GDAL (ver. >= 3.1.0).

Regards,

Jorge
