I've just found fresh ICU4R project on ruby-forge (and currently play 
with it), which seems to take care about Unicode issues including 
collation.
Maybe it's what I need, need to play more :)

Some sorting fun:

require 'ustring'
["z", "a", "ó", "o", "b", "y"].collect {|s| s.to_u}.sort {|a,b| 
UString::strcoll(a,b, "lv")}.collect {|v| v.to_s}
=> ["a", "b", "y", "o", "\303\263", "z"]
UString::strcoll("ÆSS".u, "aeß".u, "de", 0)
=> 0
"Iñtërnâtiônàlizætiøn".u.chars("").sort{|a,b| UString::strcoll(a, 
b)}.uniq.join("|")
=> à|â|æ|ë|i|I|l|n|ñ|ô|ø|r|t|z
puts a = "Iñtërnâtiônàlizætiøn".u.upcase!
=> IÑTËRNÂTIÔNÀLIZÆTIØN
v = a.search("national".u, "en", 0, nil, nil)
=> [5..12]
puts a[v[0]]
=> NÂTIÔNÀL
