Regular expression exclude µ from [\W_]

Question

I have to replace all not alphanumeric character ("_" included) and i had success with :

.replaceAll("[\\W_]", "%");

Now I need to exclude from that regex the greek char especially µ .

I had no success with "^", how can i do that?

Thanks a lot

You could try this:

[^a-zA-Z0-9-()/\s\p{IsGreekandCoptic}]
