Hmm, okay. It seems to just use Python's unicode escape syntax, instead of what the standard says. But the package does support things like the complex character classes, and identifying word boundaries. (The algorithm for identifying word boundaries in most languages without ASCII/English assumptions is quite complex and useful, as I can say from having tried to reinvent half of it before learning about the standard and the regex package. It's not a panacea -- it won't do anything useful with languages where word boundaries require lexical knowledge, like Chinese, Japanese, and Thai -- but other than that it handles all the edge cases you never would have thought of.)
