Examples of java.nio.charset.CharsetEncoder.onUnmappableCharacter()

java.nio.charset.CharsetEncoder.onUnmappableCharacter()
Set this encoder's action on unmappable character error. This method will call the {@link #implOnUnmappableCharacter(CodingErrorAction) implOnUnmappableCharacter}method with the given new action as argument. @param newAction the new action on unmappable character error @return this encoder @throws IllegalArgumentException if the given newAction is null
