How to escape slashes in JRSFlowInvoke command construction?

Anybody is aware, how to avoid call REST errors, when passed value contains slash? E.g. in below line, the call will fail with an error: "path not found" . Note: I replaced all vars by fake values :).

 

java -jar "C:\Program Files\Hewlett-Packard\Operations Orchestration\Studio\tools\JRSFlowInvoke.jar " -u USER -ep ENCRPTPASS "">SERVER:PORT/.../FLOWUUID

 

Anybody knows? Thanks.
