Jaehong Choi updated SPARK-8951:
--------------------------------
Description:
Spark gives an error message and does not show the output when a field of the
result DataFrame contains characters in CJK.
I found out that SerDe in R API only supports ASCII format right now.
So, I fixed SerDe.scala a little to support CJK as the patch attached.

people.json
{"name":"가나"}
{"name":"테스트123", "age":30}
{"name":"Justin", "age":19}
df <- read.df(sqlContext, "./people.json", "json")
head(df)
Error in rawtochar(string) : embedded nul in string : '\0 \x98'

val len = value.length
out.writeInt(len + 1) // For the \0
out.writeBytes(value)
