Description
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`.
