Translating escape sequence

[Phil Davis]

Maybe right after you import the JSON data, preprocess it with something 
like this:

set the lineDelimiter to "\u"
repeat for each line tLine in tJsonData
     put numToCodePoint("0x" & char 1 to 4 of tLine) & char 5 to -1 of 
tLine after tNewData
end repeat
put tNewData into tJsonData

Then go on your merry way. Would that work?
