beginner

I am trying to use regex.replace to strip out unwanted characters, but I need to account for spaces:

string asdf = "doésn't work?";
string regie = @"([{}\(\)\^$&._%#!@=<>:;,~`'\’ \*\?\/\+\|\[\\\\]|\]|\-)";
Response.Write(Regex.Replace(asdf,regie,"").Replace(" ","-"));

returns doésntwork instead of doésnt-work

Ideas?

Thanks!
