Hjson cpp library renders multi-line strings as single-line with escape newline characters \n in Windows Qt6.9 C++ desktop text editing application

[P5music]

Hello, hjson is very useful for my project.
I also created a Qt6.9 C++ application as an authoring utility for my project that uses the hjson cpp library and includes direct hjson text editing features to some extent.
I compiled it on Windows and on Linux.
Unfortunately the Windows version behaves unexpectedly as to multiline strings: when the hjson text is created out of a json object, the multiline strings are not rendered as
'''
this is
a
multiline
string
'''
as expected
but as
"this is\na\nmultiline\nstring".
This is not usefult at all because I created an app with an internal editor so I need that the text is correctly formatted.
In addition I can say that the json object is created from a hjson text that has those multiline strings in the correct form for sure.
Is it an issue or do I have to set some parameters explicitly for the Windows versions?
Linux version works fine as to multiline rendition.
Best regards.
