Issue #2255 has been updated by usa (Usaku NAKAMURA). Description updated I think that if -Eutf-8 is specified ARGV should be parsed from GetCommandLineW() and converted to UTF-8. But it's difficult to change ruby with keeping compatibility. I'll try it till code freeze, but I can't promise that it will be in time for 2.0. ---------------------------------------- Feature #2255: unicode parameters cannot be passed to ruby https://bugs.ruby-lang.org/issues/2255#change-31792 Author: vo.x (Vit Ondruch) Status: Assigned Priority: Normal Assignee: usa (Usaku NAKAMURA) Category: M17N Target version: 2.0.0 =begin On windows, Ruby should provide wmain to allow passing unicode parameters (especially file paths are of interest). =end -- http://bugs.ruby-lang.org/
