Hi there,

Can anyone help me change two-byte char into a bit array.
Otherwise how can I change a char #\A into a bit array.
I'd like to do some bit operation such as "shift 3 bits left".

Thanks in advance,

Kyongho Min

How about doing something like

(ash (char-code #\A) 3)

instead?

  Can you do that on a bit array?  I have always missed the ability to do
  such useful things on bit arrays.

  You could probably work with the code-value of the character.
  char-code produces an integer that should be amenable to bit-shifting.
