I too would be surprised.

What might make sense is packing 3 20-bit (or 21-bit) characters in a 64-bit long.
That would use 2.67 bytes per character and be quite friendly to
modern hardware.  Almost certainly faster that using 32 bits per character,
due to better locality.

Probably not a good choice for Kawa, though, since I think it is more important
to implement the java.lang.CharSequence interface efficiently.
