This is as specified in the pcre.3 man page in the section entitled "General
comments about UTF-8 mode":
6. The character escapes \b, \B, \d, \D, \s, \S, \w, and \W correctly
test characters of any code value, but the characters that PCRE recog-
nizes as digits, spaces, or word characters remain the same set as
before, all with values less than 256. This remains true even when PCRE
includes Unicode property support, because to do otherwise would slow
down PCRE in many common cases. If you really want to test for a wider
sense of, say, "digit", you must use Unicode property tests such as
\p{Nd}.
I will add extra words to point out the this affects \b as well, because \b is
defined as the boundary between a character than matches \w and one that does
not.
