Yes, I mean the return value.

I can't use Iconv because the script should work with any locale.
This is the code:

  require 'rexml/document'

  [...]

  include REXML

  @atom = Document.new
  entry = Element.new 'entry'
  entry.attributes['xmlns'] = 'http://www.w3.org/2005/Atom'
  @atom.elements << entry
  @atom << XMLDecl.new

  e = Element.new 'title'
  e << Text.new(`dcop amarok player title`)
  entry << e

XML tag text should be in UTF-8.

Thank you.
