java regex not working

Why this regex isnt working for non-word and non-digits like this开发者_运维问答: )(ª º ?

sentence.split("[^(\\p{L}\\p{N})]");

Is it suposed to work or not?

PS: I can't find any information either on SOF or in the web

A better description of the problem would be nice, but I'm guessing you're looking for:

sentence.split("\\W+");
