Package paths with spaces don't work with rosbash?

edit

The location of the package I am working in is

/host/Users/Mark\ Won/Documents/School\ Work/College/Junior/Junior\ 2nd\ Semester/CSE\ 468/workspace/tutorials

I have added the following to my ~/.bashrc

export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:/host/Users/Mark\ Won/Documents/School\ Work/College/Junior/Junior\ 2nd\ Semester/CSE\ 468/workspace/

However, when I try to run roscd tutorials, I get the following error:

bash: cd: /host/Users/MarkWon/Documents/SchoolWork/College/Junior/Junior: No such file or directory

Does anyone know how to get package paths with spaces in the name to comply with the rosbash suite?

---------UPDATE: I've tried adding the following to my ~/.bashrc, but to no avail:-------

export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:"/host/Users/Mark\ Won/Documents/School\ Work/College/Junior/Junior\ 2nd\ Semester/CSE\ 468/workspace/"

and

export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:"/host/Users/Mark Won/Documents/School Work/College/Junior/Junior 2nd Semester/CSE 468/workspace/"

and

export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:"\"/host/Users/Mark Won/Documents/School Work/College/Junior/Junior 2nd Semester/CSE 468/workspace/\""

and

export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:"/host/Users/Mark\\ Won/Documents/School Work/College/Junior/Junior\\ 2nd\\ Semester/CSE\\ 468/workspace/"

and

export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:/host/Users/Mark\\ Won/Documents/School Work/College/Junior/Junior\\ 2nd\\ Semester/CSE\\ 468/workspace/
