[jira] [Commented] (FLINK-20773) Support to parse unescaped control chars in string node

["Jark Wu (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-20773?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17260273#comment-17260273 ] 

Jark Wu commented on FLINK-20773:
---------------------------------

After an offline discussion with [~xiaozilong], we both think that we don't need to introduce an option for this feature. We can enable to allow unescaped control chars by default, befcause it doesn' have side effect.
