Hsin-Ying Lee commented on NIFI-8417:
-------------------------------------
[~pvillard], this is not regression
I set it to be blocker due to any users use the emoji in UI will broke the
flow.xml to be invalidate, and the nifi will not be able to reload the flow
I'm not sure if I misuse the blocker
> emoji in processor group name cause nifi to not start up
