-----------------------------------
Summary: support CJK characters in collect()
Key: SPARK-8951
URL: https://issues.apache.org/jira/browse/SPARK-8951
Project: Spark
Issue Type: Bug
Components: SparkR
Reporter: Jaehong Choi
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'

{code:title=core/src/main/scala/org/apache/spark/api/r/SerDe.scala}
// NOTE: Only works for ASCII right now
def writeString(out: DataOutputStream, value: String): Unit = {
val len = value.length
out.writeInt(len + 1) // For the \0
out.writeBytes(value)
out.writeByte(0)
