The current URLEncoder's Predicate for DONT_NEED_ENCODING is based on BitSet, which is actually a table lookup. The actual performance may not be as good as microbench.
The character value range of DONT_NEED_ENCODING is between [45-122]. We can construct two long type constants to do the work of BitSet. This can improve performance by about 7% to 30%.
