ermm,
this is the situation,
i have a txt file, it contains
[
{
"cmdType":"G",
"row":0,
"col":2,
"ans":"心",
"cmd":"C",
"qNum":19
},
{
"cmdType":"G",
"row":1,
"col":1,
"ans":"心",
"cmd":"C"
}
]
i need to parse that and get one of the json object that inside that
json array and send that json object as string to client. the code
that i posted on the first post only works when there is no chinese
character in it.
this is the exception i get when it has chinese character in it.

{
"cmdType":"G",
"row":1,
"col":1,
"ans":"心",
"cmd":"C"
}
out of the json array and send it as string to client.
