When attempting to use p4publish in Pipeline I hit an issue on workspace creation.

This can be worked around by setting the workspace separator to something compatible with P4 (e.g .-Dhudson.slaves.WorkspaceList=_), but requires a service restart.

P4: Unable to setup workspace: com.perforce.p4java.exception.RequestException: Error in client specification.
Embedded special characters (*, %%, #, @) not allowed in '/home/user/workspace/HM2CQY2DVQKDT7X3THI25H2D7XY252WQ3FWDJ7ISG34U4S7B2K7A@2'.

I'm not sure if the same solution from JENKINS-29387 would work or if this is incompatible with publishing.
