>
> Current, SparkSQL `initCap` is using `toTitleCase` function. However,
> `UTF8String.toTitleCase` implementation changes only the first letter and
> just copy the other letters: e.g. *sParK* --> *SParK*. (This is the correct
> expected implementation of `toTitleCase`.)
> So, The main goal of this issue provides the correct `initCap`.
