    You wouldn't normally use the ordinary C string type to encode a UTF-16
    (not UCS-2, please) or UCS-4 string. They're not meant for that, for
    exactly the reason your question implies: incidental zero-bytes will
    cause premature termination of the string, because almost all C
    implementations assume an 8-bit encoding.

    The solution is either to use UTF-8, or use "wide character" strings
    based on 16-bit (or, less likely, 32-bit) "character" units.
