I installed "mysql-4.1.7-win.zip" & "MyODBC-3.51.10-x86-win-32bit.msi" on Windows2000. When I run "MySQLInstanceConfig.exe", I select "big5" at "Manual Selected Default Character Set/Collation".
I run the sample code which was posted on "http://dev.mysql.com/doc/mysql/en/ADO_-_rs.addNew.html" under "Microsoft ActiveX Data Objects 2.8 Library".
When the program run to the block: 

  'rs update
  rs.Open "SELECT * FROM my_ado"
  rs!Name = "update"
  rs!txt = "updated-row"

,get an error message:

[MySQL][ODBC 3.51 Driver][mysqld-4.1.7-nt]Illegal mix of collations(big5_chinese_ci,IMPLCIT) and (latin1_swedish_ci,COERCIBLE) for operation '='

If I select "Standard Character Set" at "MySQLInstanceConfig.exe" setup screen, everything is O.K.

How to repeat:
Just select "big5" at "Manual Selected Default Character Set/Collation" when 
run "MySQLInstanceConfig.exe", the error must be back!

To use a different character set with Connector/ODBC, it is necessary to specify it as part of the DSN or connection string, which is a new feature in the upcoming 3.51.17.

Noted in 3.51.17 changelog.

It is now possible to specify a different character set as part of
the DSN or connection string.
