conversion of notes.ics in a text format

Thursday, 21 July 2016

Hello
after last upgrade of Fedora23 => Fedora24
I lost my knote note, I had only one note but full of precious notes
I have an old version:
/home/maumar/.kde/share/apps/knotes/notes.ics
but it is full of \n
is there a perl line for converting \n into cr?
perl, python, sed ...whatsover...

This way I can get my note back; old, but better than nothing :)
Thanks in advance
