Remove non alphanumeric characters while keeping European letters

Hi guys,

I am trying to remove all non alphanumeric characters from a string but when i do regex(/W) with the node “string replacer” i loose all accentuated/ european letters like “á”. Is there a way to control this.

Safa, (/W) is equivalent of [^a-zA-Z0-9_]
So add accentuated characters to the list to preserve them.
