There are two scripts in this commit:
* 202008040100_IDEMPIERE-3862.sql - updates the whole core as of today, changing the columns VARCHAR2...BYTE and NVARCHAR2 to VARCHAR2...CHAR
* 202008040114_IDEMPIERE-3862.sql - updates the non-core tables, same algorithm, the first script was generated using this second for the core
** in case somebody doesn't want the second script to run on their database can simply change the line 39 to ->dryrun varchar2(1) := 'Y';
