capitalize and utf8 international symbols

Hi there,

Being a relatively happy Rails user I suddenly noticed that
string#capitalize and friends do not play well with international
characters well. Sample console session:

$ ./script/console
Loading development environment (Rails 2.2.3)


=> "UTF8"


=> "яблоко"

Where "Яблоко" was expected (Russian word for "Apple").

I've googled for a workaround and found this:


=> "Яблоко"

but does it really need to be so ugly? Everyone else doing this?

I'm on Ubuntu 9.10 with Rails-2.2.3 and ruby-1.8.7.

Sadly, google groups scrambled the symbols, but take my word -- it
doesn't work with plain capitalize, but works only through mb_chars.

Am I doing something wrong? Can I (should I) monkey-patch String
class to pipe capitalize et al. through mb_chars?
