This package supports Unicode 4.0, although \w, \W, \d, \D, \s, and \S support only ASCII. You can use the equivalent Unicode properties \p{L}, \P{L}, \p{Nd}, \P{Nd}, \p{Z}, and \P{Z}. The word boundary sequences—\b and \B—do understand Unicode.
For supported Unicode properties and blocks, see Table 2. This package supports only the short property names, such as \p{Lu}, and not \p{Lowercase_Letter}. Block names require the In prefix, and support only the name form without spaces or underscores, for example, \p{InGreekExtended}, not \p{In_Greek_Extended} or \p{In Greek Extended}.
