Encode korean data of queryset with serialize 'json' got problem

[최규범]

i'm started django and python this week,

i've got some problem when i encode queryset to json string.

i tried serializers.serialize('xml', queryset),

it returns my korean data with no problem

but, 

serializers.serialize('jsonl', queryset) returns korean string to unicode string ( ex: \uaca8\uc6b8\ud559\uae30 )

i cant find any ways to fix this problem

plz help...
