UTF-8 is a little more complex than that. Chars 0-0x7F are represented by one byte, 0-0x7F. Beyond that characters are represented with 2 to 4 bytes. This means that for every character there are multiple comparisons and shifts performed, with some extra bits being set or cleared for certain characters. UTF-16 on the other hand, being the native encoding for Java, is written one char at a time without transcoding - no shifts, no comparisons, no bitmasks. It's just a straight write of chars. You can't possibly do better than that in terms of processing speed. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4150822#...
