Investigation into traces of J2SE startup time has shown that sun.io.CharacterEncoding spends roughly 60 milliseconds during core libraries startup performing roughly 700 HashMap.put() operations mapping the name of an encoding to the name of the byte-to-character converter used for that encoding. At least the common US-ASCII case should be done up front and most of these calls avoided.
