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.

{"name":"가나"}
{"name":"테스트123", "age":30}

df <- read.df(sqlContext, "./people.json", "json")

Error in rawtochar(string) : embedded nul in string : '\0 \x98'

out.writeInt(len + 1) // For the \0
