> The current implementation of *capitalize*, *uncapitalize* and *initials* in *WordUtils* calls *isDelimiter* for every character and/or codepoint and isDelimiter loops through the array of delimiters to check for the  occurrence. This is a bit inefficient and results in O(nk) complexity and it can be reduced to O( n )[if n>k] or O( k ) [if k>n].
