[gdal-dev] UTF-8 and layer names

[Nyall Dawson]

Hi list,

While looking into https://github.com/OSGeo/gdal/issues/2894 , I hit a
bit of confusion about the expected encoding of OGR dataset layer
names.

I've been looking over the related RFCS:
- https://gdal.org/development/rfc/rfc5_unicode.html
- https://gdal.org/development/rfc/rfc23_ogr_unicode.html
- https://gdal.org/development/rfc/rfc30_utf8_filenames.html

and I can't see any mention of how layer names should be encoded, and
whether or not UTF-8 layer names are supported in current GDAL
releases.

Is anyone able to supply some clarification on this, and how extended
characters could be/should be handled in GDAL drivers?
