[gdal-dev] Issue opening RAR archive with non-latin filenames

[Rahkonen Jukka]

Hi,

Perhaps the key is in the message "to current locale." When I have seen something similar on Windows and when using my default code page 850, changing the code page into 65001 (UTF-8) has often helped. But I have never met  UTF-16BE data.

Aihe: [gdal-dev] Issue opening RAR archive with non-latin filenames

Hello,

I’m having trouble opening a RAR archive containing files with non-Latin characters using GDAL:

$ docker run --rm -v `pwd`/arch.rar:/arch.rar:ro -e CPL_DEBUG=ON ghcr.io/osgeo/gdal:ubuntu-full-3.11.3<http://ghcr.io/osgeo/gdal:ubuntu-full-3.11.3> gdalinfo "/vsirar/arch.rar"
VSIARCH: Opening arch.rar
VSIARCH: Pathname cannot be converted from UTF-16BE to current locale.
VSIARCH: Opening arch.rar
VSIARCH: Pathname cannot be converted from UTF-16BE to current locale.
ERROR 4: `/vsirar/arch.rar' does not exist in the file system, and is not recognized as a supported dataset name.
gdalinfo failed - unable to open '/vsirar/arch.rar'.

It seems the issue is related to the non-Latin filenames in the archive. Using unrar, I can extract the files and list them without any problem.
Is there any workaround to make GDAL handle such RAR archives correctly?

Thank you!
