[jira] [Comment Edited] (KYLIN-3668) Performing a cube build error
on the Chinese hive table field
[ https://issues.apache.org/jira/browse/KYLIN-3668?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16698448#comment-16698448 ]

Hi [~wxs] ,
As far as I know, hive doesn't support UTF-8 for database/table/column name yet. [https://cwiki.apache.org/confluence/display/Hive/User+FAQ#UserFAQ-DoesHivesupportUnicode?]
This is because hive needs to pass the meta
information between components, sometimes as XML sometimes as json,
and these serializations are not able to deal with complex encoding.
It is complex to support Chinese character names in Kylin and we have no plan to do this so far. Maybe table/column comments can be an alternative for you.
