This is a tricky point.

If you are using Ruby 1.9 then Oniguruma'a class /[[:alpha:]]/u should  
work.
I can remember that one could install Oniguruma's regexp engine also  
for Ruby 1.8.

By myself I tried to rewrite my regexp in a negated form, i.e. instead  
of looking for \w I wrote e.g. [^\d\s -_].
A the other way would be to look for a significant string after the  
author. Ruby 1.8 matches by /./u also the ü as single character.

If this doesn't work for you, well then you should use the Unicode  
ranges, but you can shorten it if you are only dealing with names  
written in Latin script.
