Problem with "Special Characters"

Hi All.
I´m working on a definition that uses a parsed XML file. I split the lines and use a {linefeed} panel to split the lines of an incoming “paragraph”.
The thing is that everytime I open Rhino and load the GH file, the split is completely wrong.
This kind of wrong.

but as soon as I de- and reactivate the “special characters”, everything turns as it should.

Is not really that problematic, but rather annoying… the abnormal behaviour happens once and things keep stable even with other files through the work session. If I close Rhino and open it again, it will repeat.
Is it a known bug?
