How to match unicode words with ruby 1.9?

Question

I'm using ruby 1.9 and trying to find out which regex I need to make this true:

Encoding.default_internal = Encoding.default_external = 'utf-8'
"föö".match(/(\w+)/u)[1] == "föö"
# => false

might have clues for you

You can also use the (documneted) \p{L} property:

chastell@devielle:~$ ruby -ve "p '℉üüü' =~ /\p{L}/" ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-linux] 1

Answer 2

# encoding=utf-8 
p "föö".match(/\p{Word}+/)[0] == "föö"
