No Issues that I have come across. I have a couple of Series 9 to 11 customers and have been running for a while.
Don’t know if you ever had the problem with the separation characters. If you do back in 1998 I came across the ebcdictoascii and asciitoebcdic tables had 6 characters that didn’t translate correctly….ie ! –> ] and back ] –> . So they would translate back and forth…. These tables are qascii and qebcdic on as400……
