You mentioned Roundcube earlier. I notice this in Roundcube's default main.inc.php:

  // Password charset.
  // Use it if your authentication backend doesn't support UTF-8.
  // Defaults to ISO-8859-1 for backward compatibility
  $rcmail_config['password_charset'] = 'ISO-8859-1';

...so changing that to UTF-8 may fix the problem so far as Roundcube is concerned.

But you may still face a problem with other clients. We just discussed Thunderbird's behaviour a few days back...
