One of the biggest changes between ruby 1.8.x and ruby 1.9.x is how
ruby handles strings, in non-ascii environments.

Small  example

[tasaka1 at localhost ~]$ rpm -q ruby
ruby-1.8.7.352-3.fc17.i686
[tasaka1 at localhost ~]$ ruby -e "puts 'あいう'.size"
9

v.s.

<mock-chroot>[root at localhost /]# rpm -q ruby
ruby-1.9.3.0-2.fc17.i686
<mock-chroot>[root at localhost /]# ruby -e "puts 'あいう'.size"
3

This diffecence may not be visible in ASCII world. However when
dealing with multibyte characters this change can be impact.
