I've been experimenting now a little bit with the string encoding in Twincat. According to the infosys it's an cp1252 encoding for the normal string. Shouldn't we integrate that one instead of the utf-8?
I tried it with the write_by_name function (adsSyncWriteReqEx) and now you can write with ASCII 256 and the plc shows it the right way.
It doesn't solve my problem with the utf-8 encoded Strings but at least you can write and read special characters with the normal strings.
