First of all, do you know about ror2ru google group? You'll be much
comfortable there with unicode questions...
Brief answer is: there's Unicode gem, which allows things like
Unicode#downcase(string).
Longer answer is: there's also Julian's Tarkhanov unicode_hacks, which uses
this gem for more comfortable things like string#downcase.
Even longer answer is: russian RoR community has something more organized
about this, but personally I don't know, as I'm do nothing with RoR. I use
unicode+unicode_hacks.

Should no tool be available to do downcase, upcase, and the like for
Russian what about implementing it? Doing so is not very complicated.
If you actually intend to do this please support all characters of the
Cyrillic script (quite a number of them is not used in Russian).
The full list of Cyrillic characters and their Unicode code points are
available at Unicode.org
Cyrillic: http://www.unicode.org/charts/PDF/U0400.pdf
Cyrillic supplement: http://www.unicode.org/charts/PDF/U0500.pdf
IANAL but to my understanding it is perfectly legal to use these sheets
(in contrast to buying high-price standards documents that is) for
implementing a conversion tool.
- From these sheets you can create an array of all lowercase and an array
of all uppercase letters and out of them regular expressions that match
precisely one Cyrillic letter and a hash that maps each lowercase
character onto an uppercase one and one that maps each uppercase
character onto a lowercase one. Should some lowercase or uppercase
character have no counterpart (I am not completely sure if this is the
case or not) simply exclude it.
Consider applying the standard method before applying the abovementioned
mapping.
Hope that helps a bit,
Josef 'Jupp' Schugt

Install Visual C++ (Express version is free). Then 'nmake'.

As already indicated above, you may also consider to roll your own
utf8-aware downcase method.
class String
def downcase_utf8
gsub(/./mu) do |char|
case char
when /\320\237/u then "\320\277"
when /\320\240/u then "\321\200"
when /\320\230/u then "\320\270"
when /\320\222/u then "\320\262"
when /\320\225/u then "\320\265"
when /\320\242/u then "\321\202"
else
char
end
end # gsub
end
end
Cheers,
J.K.
