I cannot reproduce this.  It works for me.  What do you get if you
type "C-x 8 RET 150", as indicated in what-cursor-position's output?

No, the code is interpreted as hex by "C-x 8 RET".  So I wonder what
went wrong in your case.  Can you show the result of "C-h l" (the
letter ell, not the digit one) after typing "C-x 8 RET 150"?
