    I don't have gzip, but I can give you the PKZip sizes, which should be
    quite similar:

    UTF-16 2,685,232 bytes
    UTF-8 2,774,356 bytes
    SCSU 2,756,470 bytes
    BOCU-1 2,772,418 bytes
    EUC-KR 2,518,201 bytes

    Note that the largest of these is only 10.2% larger than the smallest.
