因此,matz决定保留upcase并downcase限制/[A-Z]/i在ruby 1.9.1中.

ActiveSupport::Multibyte长期以来在ruby 1.8.x中经历了很棒的i18n案例String#mb_chars.

但是,当在ruby 1.9.1下尝试时,它似乎不起作用.这是我写的一个简单的测试脚本,以及我得到的输出:

$ cat test.rb
# encoding: UTF-8

puts("@ #{RUBY_VERSION} " + (__ENCODING__ rescue $KCODE).to_s)
sd, su = "Iñtërnâtiônàlizætiøn", "IÑTËRNÂTIÔNÀLIZÆTIØN"
def ps(u, d, k); puts "%-30s:  %24s / %-24s" % [k, u, d] end
ps sd.upcase, su.downcase, "Plain ruby"

require 'rubygems'; require 'active_support'
ps sd.upcase, su.downcase, "With active_support"
ps sd.mb_chars.upcase.to_s, su.mb_chars.downcase.to_s, "With active_support mb_chars"

$ ruby -KU test.rb
@ 1.8.7 UTF8
Plain ruby                    :  IñTëRNâTIôNàLIZæTIøN / iÑtËrnÂtiÔnÀlizÆtiØn …
