Your regexp seems to work. It also deals correctly with the problem of matching 2nd byte (a \0) of hypothetical 1st char (a "p\0" or "\x70\0" lets say) and 1st byte of 2nd char (a \0) that is a utf 16 null (a \0\0), rather than byte 1 (\0) and byte 2 (\0) of utf16 null. I didnt think of doing your group and multiplier to do the alignment on the utf16 strings in a regexp. Thanks.
