Sönke Liebau commented on KAFKA-4827:
-------------------------------------
There is a few more special characters that cause similar behavior: %, ?, <, >,
/, \, ...
I have blacklisted the obvious ones in the fix for KAFKA-4930 but think that a
larger discussion around naming conventions and what is and isn't allowed is
probably necessary.
