TisonKun commented on FLINK-11174:
----------------------------------

It seems we can directly extend the range of label value to utf-8. So I'd like 
to ask for a consensus on implement this feature. cc [~Zentol] and 
[~lamber-ken] since they are the most involved members.

@[~fanweiwen] for "want to be flink Commiter   Any good suggestions?", you can

contributors and community members"
