[jira] [Commented] (HIVE-4100) Improve regex_replace UDF to allow
non-ascii characters
[ https://issues.apache.org/jira/browse/HIVE-4100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13590803#comment-13590803 ]
thattommyhall commented on HIVE-4100:
-------------------------------------
The particular case I had was
regexp_replace(some_column,"[^\\u0000-\\uffff]","\ufffd")
does not work, whereas
regexp_replace(some_column,"[^\\u0000-\\uffff]","�")
does.
So we need a way to specify unicode chars in the replace string.

> There have a been a few email threads on the user mailing list regarding regex_replace UDF not supporting non-ASCII characters. We should validate that and improve the UDF to allow it. Translate UDF will be a good reference since it does that by using code points instead of characters
