When serving pages in charset ISO-8859-15 instead of default UTF-8 and rendering a form MoneyType, currency symbol (€ in my case) is shown in wrong codification (see screen captures).

As additional information, this is my code in AppKernel.php regarding charset:

/**
 * Get the framework charset
 *
 * @return string The charset
 */
public function getCharset()
{
  return 'ISO-8859-15';
}

And a link showing details of ISO-8859-15 charset, which supposedly has an euro (€) symbol. My twig template is also encoded in ISO-8859-15. A possible cause of this problem is that the source code file for money template is encoded in UTF-8, which is of course right.

I know I can override MoneyType template, but a correct solution, I think, is writing the euro symbol as the € html entity, which is charset independant.
