Thanks, I hadn't thought of using SAFE. My problem is that I encounter 
not-wellformed strings in the data, e.g. 'hello\', which break evaluation.  
But now I catch the exception and just return the string un-evaluated, 
which is fine, because those escape syntaxes are not allowed anyway.

So thanks, I've used your solution.
