Yes, it will. Just to note again that the "_" (underscore) is already
included in \w. Repeat, 'alphanumeric plus "_"'. Also, if you put the
"-" (dash) in the last sequence (just before the the closing "]"), you
don't need to escape it. You don't need the escape either for the ".",
it means literal inside character class.
So this one will work equally,
/[^\w.-]/
