Storing PDF selection

Hi

Is there a way to store serialize and store PDFselection ?

If I have a PDF View , select part of it and get the currentSelection, 
showing it tells something like
Page index = 2, Range = (0, 21]

However I do not see where I could get the range of the PDFSelection 
and later recreate a selection with this value

Thanks for helping
