Reviewed by Darin Adler.

The table has been updated in the CSS Text specification:
https://github.com/w3c/csswg-drafts/commit/9110c78e787ac8e8f85825dd0e37d0736943cdc5

The code now use code points (because some of the mapped code points
are represented by more than one code unit).
The code is careful about correctly cutting the unnecessary high level bits
for code points which are effectively represented which a single UTF-16 code unit.
