Ok, so no $KCODE --a chance to learn a little about Encodings

I am working on some 1.8 to 1.9 compatibility. I have a bit of code:

if $KCODE =~ /^U/i
  unpack_rule = 'U*'
else
  unpack_rule = 'C*'
end

$KCODE is no long effective, so what to do for 1.9?

I think I have figured it out. Given two strings to compare we can do:

if str2.encoding != str1.encoding
  str2 = str2.encode(str1.encoding.name)
end

s = str1.codepoints.to_a
t = str2.codepoints.to_a

Where #codepoints does the same as old str.unpack(unpack_rule).
