How to capture output of this code to variable to send it to iconv?
(Just like ob_start() in PHP)
# ???
p ["utf-8 string",[123,321],"another string"]
# ???
puts Iconv.conv("866","UTF-8",captured_output) # because of windows
console

You can send output to a string:
require "stringio"
strio = StringIO.new
strio.write("hello world")
strio.rewind()
puts strio.read()
old_out = $stdout
$stdout = strio
puts " goodbye"
$stdout = old_out
strio.rewind()
puts strio.read()
--output:--
hello world
hello world goodbye
