swift object path with ";"

########################################################
# object path containing a folder named semicolon (";")
########################################################

This is the folder structure where my object "obj" resides on my local machine:
f1
 |_f2
    |_";"
        |_obj

#creating a container named "test_container"
swift@sandbox-nt:~$ swift post test_container

#uploading object "obj" into "test_container" using its absolute path
NOTE: swift will create the object and name it with the absolute path that we mention. this behaviour can be overrriden.
swift@sandbox-nt:~$ swift upload test_container f1/f2/";"/obj
f1/f2/;/obj     --> name of the object

#making a folder to download "obj" and check if multiple folders are getting created
swift@sandbox-nt:~$ mkdir downloads
swift@sandbox-nt:~$ cd downloads/

#download "obj" by specifying its container name ("test_container") and the name of the object
swift@sandbox-nt:~/downloads$ swift download test_container f1/f2/;/obj
Object 'test_container/f1/f2/' not found  (I forgot to add the quotes to the semicolon for shell to not ignore the the semicolon)
bash: /obj: No such file or directory
