What changes were proposed in this pull request?
This PR is proposed for HIVE-28728, when under non-UTF8 default charset, STR_TO_MAP() returns garbled characters with vectorization enabled.
Why are the changes needed?
Using default non-UTF8 charset should not give different behaviours (garbled characters vs correct characters) when vectorization is on/off.
This also aligns with the Jira HIVE-28544.
Does this PR introduce any user-facing change?
No.
How was this patch tested?
Created str_to_map_utf8.q and tested with TestMiniTezCliDriver TestMiniLlapCliDriver with corresponding settings
