I did this for a project (way back in Rails 1.1.6)

$KCODE = 'UTF8'
require 'jcode'

class String
   def first(limit = 1)
     self.match(%r{^(.{0,#{limit}})})[1]
   end
end

You'd still have to assign this, but:

irb> name = "P\303\245l Bergstr\303\266m"
=> "P\303\245l Bergstr\303\266m"
irb> puts name
Pål Bergström
=> nil
irb> puts name.first(2)
På
=> nil
irb> puts name.first(3)
Pål
=> nil
irb> puts name.first(12)
Pål Bergströ
=> nil
irb> puts name[0...12]
Pål Bergstr
=> nil
irb> puts name[0...2]
P?
=> nil
irb> p name[0...2]
"P\303"
=> nil

I hope that helps you.
