Characters of ISO-8859-1 with two byte representation in UTF-8 encoded configuration files such as german umlauts should work

Current Situation

• We assume that we have a permanent order which configuration file is UTF-8 encoded and it contains two byte characters from ISO-8859-1 such as german umlauts

  <params>
      <param name="body" value="body with äöü"/>
  </params>
  

• This parameter is processing well for the first run of the Order
• In each further run of the order äöü is used
• If the order is touched again and thus reloaded, äöü will be used again for the next run.

Desired Behavior

Two byte characters of ISO-8859-1 from UTF-8 encoded configuration files such as german umlauts should always work.
