Scrub that: these only work for characters over U+00ff.
Try these instead:
utf16be =. [:,a.{~[:}.256#.(^:_1)999,3 u:]
utf16le =. [:,[:|."1 a.{~[:}.256#.(^:_1)999,3 u:]
a.i.utf16le 'hello there'
104 0 101 0 108 0 108 0 111 0 32 0 116 0 104 0 101 0 114 0 101 0
a.i.utf16be 'hello there'
0 104 0 101 0 108 0 108 0 111 0 32 0 116 0 104 0 101 0 114 0 101
