\w doesn't match non-ASCII letters

oocms=3D# select '=D1=84' ~ '^\\w$';
 ?column?
----------
 f
(1 =D0=B7=D0=B0=D0=BF=D0=B8=D1=81=D1=8C)

or

oocms=3D# select '=C3=A4' ~ '^\\w$';
 ?column?
----------
 f
(1 =D0=B7=D0=B0=D0=BF=D0=B8=D1=81=D1=8C)

both should return true, as does=20

oocms=3D# select 'n' ~ '^\\w$';
 ?column?
----------
 t
(1 =D0=B7=D0=B0=D0=BF=D0=B8=D1=81=D1=8C)

Thanks.
