Special Characters in values

i find:

i have a predicate with value: sdcsd\u0000dsfdsfdsf

and then i exported database from dgraph into RDF, the value changed to:

“<_:uidcea> “sdcsd\x00dsfdsfdsf”^^xs:string .”

the problem is that: i can not use bulk loader to import this, it has a error:

while lexing <_:uidcea> <name> "sdcsd\\x00dsfdsfdsf"^^<xs:string> .: Invalid escape character : 'x' in literal while parsing line "<_:uidcea> <name> \"sdcsd\\x00dsfdsfdsf"^^<xs:string> ."

it seems that it can not parse this special value : \u0000 , how should i do?
