Escaped control characters in strings with Fuseki

Hi,

when posting turtle data with newlines, for example

lsr:82b9a3b5-6cba-4bd3-95c3-d309e8362c5e
         dcterms:title
                 """2380
Bellow Control Valve"""@en .

it's returned for construct query in escaped form

lsr:82b9a3b5-6cba-4bd3-95c3-d309e8362c5e
        dcterms:title
                 "2380\r\nBellow Control Valve"@en

Is it possible to get strings back in unescaped form? If not, is there a 
list of escaped characters available?

Not change the output - because this form preserves "\r\n" vs "\n" 
newline style - i.e. it is safer.

Parse the result. The escapes will be processed.

See the Turtle spec.
