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

This irb example may help:
±---------------------------------------------+
| >> pipe = IO.popen(“echo ‘drop him a line’”) |
| => #IO:0xb7a7b450 |
| >> capture = pipe.read |
| => “drop him a line\n” |
| >> puts capture |
| drop him a line |
| => nil |
| >> |

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
