If the current path contains diacritics, it may crash with some UTF-8 locale and format: ``` % pwd /tmp/1000/plop-2832509/ééé % touch foo % ar rcs foo.a foo % LANG=C aunpack foo.a x - foo foo.a: extracted to `Unpack-2549' (local file exists) % LANG=fr_FR.UTF-8 aunpack foo.a Wide character in setenv at /usr/bin/aunpack line 33. ar: /tmp/1000/plop-2832509/ééé/foo.a: Aucun fichier ou dossier de ce nom aunpack: ar ...: non-zero return-code ``` It's not even about the name of the archive or the files inside the archive, it fails merely because of current directory path!
