It is worth poitingpointing out that Kotlin, unlike Java, has <code>String.trimStart</code> and <code>String.trimEnd</code>. More importantly though, Kotlin’s <code>String.trim</code> actually trims whitespace as defined by Unicode, whereas Java’s just strips Unicode control characters.
 
Kotlin’s <code>trim</code> family of functions also optionally accept a predicate, which can further customize the stripping behavior, if Unicode whitespace is not what is desired.
