First, uninstall 1.9.2 and install a recent 1.9.3 (p125 or later) from 
http://rubyinstaller.org/ If you're using the 1.9 family on Windows, 
purge every other version except 1.9.3p125 or higher.

Here's what I get on Win7 32bit in a cmd.exe shell...

C:\Users\Jon\Documents\RubyDev\sandbox>chcp
Active code page: 437

*** encoding_1.rb file contents ***
# encoding: UTF-8
utf8 = "Some accented text áóíúé with regular text."
puts utf8

...and without the `# encoding: UTF-8` at the top of the file:

If you want toy with poor old cmd.exe, try using the `type` (like `cat`) 
command to list out `encoding_1.rb` after switching different codepages.
