Description

"Hello".match(/[\w]*/)
=> #<MatchData "Hello">

"Привет".match(/[\w]*/)
=> #<MatchData "">

"Привет".match(/[А-Яа-яЁё\w]*/)
=> #<MatchData "Привет">

Non word character type \W behaves similar.

=> #<MatchData "a">
> "aér".match /[[:word:]]+/

The documentation of Regexp is awesome in Ruby 1.9, have a look ;)
