Addressbook next encoding issue

Hi again, it would have been too nice to be true, but there is the next issue in the chain. When I wrote yesterday "I tested", I meant I build and installed deb and restarted the virtual machine. I checked the address book and all the utf8 chars were still in place. Today however I pressed the reload button and got all the utf8 converted into ? signs (which is pointing to ascii conversion). Looking into the code there is vcardformat and vcardformatimpl. I finalized the vcardformat test which checks save and load, but all looks good. I am going to write a test for vcardformatimpl, but I am not even sure I'm looking into the right direction. Where and how do I find what is behind the reload button? thanks
