https://cust-projects.seeburger.de/redmine/issues/24919 → PO Down/ Upload leads to “???” in Supplier comment

• - Create new branch
  • + Create branch story/AIRS-234_QuestionMarksInComment
  • - Change version in POMs
• - Analyze what is to do
  • + Check it on DEV (!) → maybe it is local setting from Mr.Kruppa → it's not a local settings, but…
  • - It seems, that it is the setting of the property “file.encoding”, which is set to “ISO8859_1” on the DEV. So this charset does not contain '€' signs. Burkhard is now checking whether it will work, if he sets the encoding to “UTF-8”.
• - Fix → Burkhard will do it through configuration
• - Test → wait for Burkhard
