unset LC_CTYPE - Remark : see the possible values for LANG in the directory - - /usr/lib/locale : Fedora 2 / Solaris 8 - - /usr/share/locale : OpenBSD / Debian / FreeBSD / MacOS X / Mandrake 10.1 / NetBSD - - On Linux, to display the available locales : locale -a - - p7zip relies on LC_CTYPE and then on LANG to convert name to/from UNICODE. - the command "locale" should display these environment variables. - you can also do "echo $LC_CTYPE" and "echo $LANG". - - If you do not plan to export your archive, you can use the flag "-no-utf16". - Usage : - 7za a -no-utf16 archive.7z dirOrFile1 ... dirOrFileN - 7za t -no-utf16 archive.7z - 7za l -no-utf16 archive.7z - 7za x -no-utf16 archive.7z - - - ignores Windows file access permissions (files are created with default permissions) - - see also TODO file. - -DEVELOPPER CORNER: ------------------- - - - WaitForMultipleObject has no equivalence on Unix. - - Events don't exist. - - sizeof(wchar_t) = 4 with GCC (2 with MS VC++) - - "FIXME" in source code indicates that you should add codes to better handle all cases. - - - "FIXED" in source code indicates that the original code has been changed to work in Unix environment. - - see also TODO file. |
