How to ignore escape sequences?


let's say I do have a sentence in my source segment which I want to translate. Beside the regular sentence however I've got escape sequences, "\n" for example. I noticed, that the AT for example sometimes struggles with these escape sequences ( "\n\nSentenceA" becomes "\n\SentenceA" for example). 

Is there a way I can make the AT ignore the escape sequences? GoogleAPI for example puts spaces like "\ n \ n " or sometimes "\ N \ N".
I feel parser rules won't help me with that. Xpath probably neither? Has anyone had similar issues and has a solution for this? Because if you translate an xml with quite a few of those escape sequences, you really will miss some of those mess ups and end up with problems later on (when the line break doesn't appear, for example). 


Appreciate any help :)
