Pages with / (slash) in the name are saved in the wrong path in a XAR

For example if I have a page named "xMyFCHlw42O1o2+O/6/RGUycbMw=.xml " located in space "License.Certificates" and I export this page, it'll be saved in the XAR as:

License/Certificates/xMyFCHlw42O1o2+O/6/RGUycbMw=.xml 

And thus when I unzip the XAR it'll be located in the wrong directory on unix since the "/" in the page name is considered as a page separator:

License/
  |_ Certificates/
    |_ xMyFCHlw42O1o2+O/
      |_ 6/
        |_ RGUycbMw=.xml 

Thus when exporting a page in a XAR the "/" needs to be handled and possibly replaced by something else.
