I think the problem is that the job execution is initiated by Apache. The Jobe install instructions show how to set the Apache envvars (environment variables) to change from the default C/ASCII environment to something that's UTF-8 aware. It's those environment variable settings that are controlling the jobe task execution, not the OS/Shell environment.
