Correct. Rounded to two decimal places, it would still be 4.09 bits.

To counter the impression that surrogates give you 5 additional bits,
which they don't. That they give 4 additional bits is much closer to
truth. I would by 4 cans of beer, and accept that I owe someone a drop
- especially since me and my guest won't drink more than 2 cans
tonight.
