charset problem with SQL Server

[Joe Murray]

On reverse engineer schema I get:
Error: UnicodeDecodeError: 'utf16' codec can't decode byte 0x65 in position 22: truncated data

I have a newly installed WIN10, SQL Server 2017, with a restored recent database backup from Raisers Edge in an old format. The Collation of the database is SQL_Latin1_General_CP1_CI_AS. I believe this indicates:
charset latin 1
CP1 stands for Code Page 1252
CI case insensitive comparisons
AS accent sensitive

There are strings with accents, as well as image and other binary data in the db. I am not sure why 0x65 causes error since I was under the impression it is just a small e in utf16 like in utf8 and ucs2.

I have installed MySQL 8.0.13 and MySQL 8.0.13 with installer. SHOW CREATE DATABASE aore_new; yields result
'aore_new', 'CREATE DATABASE `aore_new` /*!40100 DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci */'


Using ODBC Administrator I tried three driver options for configuring a System DSN:
- ODBC Driver 13 for SQL Server (Version 2017.140.2002.14)
- SQL Server (Version 10.00.17763.01) and
- SQL Server Native Client 11.0 (version 2011.110.6540.00).

I tried varying the option Perform translation for character data with no change in the result.

How should I configure a things in order to migrate data into MySQL from SQL Server.
