Hi Guille, Sven, Esteban and Everyone, Can someone (dis)confirm that the Zinc-Character-Encoding-Core package is considered part of the pharo "core" image? The reason I ask is that I'd like to know whether the File class (which is part of the Files-Core package) can count on ZnUTF8Encoder (which is part of the Zinc-Character-Encoding-Core package) being present in the image. If File can count on ZnUTF8Encoder being present then for FileAttributes I will make UTF8 encoding / decoding available from File, and thus UTF8 file names will be supported. If it can't count on ZnUTF8Encoder being present then File will only be able to handle ascii file names (unless the names are somehow already UTF8 encoded) and support for UTF8 file names will effectively be restricted to FileSystem. Thanks, Alistair
