"Why jcode.rb?" by shugo

I'm wondering why so many people use jcode.rb on Rails. jcode.rb may break other libraries because it redefines some methods of String. So I recommend you not to use jcode.rb if it is not really necessary.

In many cases, you can use Regexp instead. For example,

require "jcode"

$KCODE = "u"
s.each_char do |ch|
  puts ch
end

This code can be rewritten like this:

s.scan(/./mu) do |ch|
  puts ch
end

I admit that the latter is less readable than the former. M17N features or selector namespace will fix this problem completely in the near future, I hope.
