Hi,
I have some problem about table ddl generation.
It shows Thai comment in "Columns" tab correctly.

However in "SQL" tab It does not properly show.

The output from dba_col_comments view also shows correctly.
This behavior is found in 18.4 and 18.2 but not in 4.
Is this bug or just misconfigure? Please advice.
Best Regards,
Tawatchai R.
