Subject: How to upcase/downcase utf-8 chars?

Hi,

I want to upcase/downcase utf-8 characters. How to do it with ruby?

I googled the web with no satisfying results. I also installed
character-encodings (0.4.1) but have no idea how to use it (the
documentation is really pure).

If I put " require 'encoding/character/utf-8' " line to my script I
get:

"(...) in `require': no such file to load -- encoding/character/utf-8
(LoadError) (...)"


Docs say:

"To compile:

$ rake

To test:

$ rake spec"


I get:

"(in (...)/character-encodings-0.4.1)
rake aborted!
no such file to load -- spec/rake/spectask
(...)/character-encodings-0.4.1/rakefile:10
(See full trace by running task with --trace)"


Docs say:

"It’s basically the following:

require 'encoding/character/utf-8'

str = +"äbc"
str_that_is_the_same_as_previous_str = u"äbc"

There’s no install task yet, so until then, just load Ruby as follows:

$ ruby -Ilib:ext

and you’ll be able to require the library as shown above."


I get:

"(...) in `require': no such file to load -- encoding/character/utf-8
(LoadError) (...)"

...

Could anyone tell me how to upcase/downcase utf-8 characters? Is it
that hard?! it should be damn simple as it is a damn simple feature...

Greetz,
Timo
