Client character set 'utf8' is different from server character set 'latin1'

I cannot connect to my mySQL server.
Computer:
Windows 7
NLS_LANG=AMERICAN_AMERICA.WE8MSWIN1252
I get the following error:
Devart.Data.MySql.InvalidCharsetException
Client character set 'utf8' is different from server character set 'latin1'.
Stack Trace:
at Devart.Data.MySql.MySqlConnection.i()
at Devart.Data.MySql.MySqlConnection.Open()
at Quest.Toad.Db.Connection.OpenConnection(IDbConnection connection)
at Quest.Toad.MySQL.MySQLConnection.OpenConnection(IDbConnection connection)
at Quest.Toad.Db.Connection.AllocConnection()
at Quest.Toad.Db.Connection.Connect(Boolean notify)
at Quest.Toad.Db.Provider.BackgroundConnector.CreateBackgroundConnection()
Why would it think my client is UTF8?

Toad for MySQL will unfortunately always try to connect using Unicode because it needs to know the encoding used on the data received and the MySQL server's character sets are not a 1-1 match with what is supported on Windows.

So how can I connect to my database? or can I only connect to UTF8 databases now no matter what?

What version of the database are you using?

unfortunately...
version: 4.0.17-log
Before I switched to Windows 7, I had XP and Toad for MySQL (probably an older version) worked fine. Is my mySQL version too old perhaps?

A lot of things changed in MySQL in regards to how it handles character sets in both version 4.1 and then even more for version 5.0 and later.
That said I think this might be a bug in our application where we are having issues with version 4.0 of Toad for MySQL. We should still be able to connect to it. Unfortunately I don't think there is any way for you to work around this until we fix the issue (It should start working if you upgrade to something later than 5.0 but I can totally understand how that is a pretty drastic change just to get a tool to work).

Thanks, I appreciate it. We're going to upgrade mySQL soon (I hope).

In our defense MySQL 4.0 is pretty ancient. :)
Our test matrix do include testing against MySQL 4.1 but that is as old as we go currently.

Changing the character set on the server is out of the question, since you need to do it per table, and there are serious ramifications to attempting this with regard to query compatibility. It will break joins and all sorts of stuff.
However you can change your windows character set to latin1 in toad and give that a shot.
Start toad
Tools | Options | Editor | General | File Encoding Type
Change UTF-8 to Western European (aka Latin-1)
Please let me know if that works for you

That setting unfortunately only applies to how the editor opens and saves files, not to the MySQL connection.

The same problem happens to me with mysql 6.0.1.1723
Devart.Data.MySql.InvalidCharsetException
Client character set 'utf8' is different from server character set 'latin1'.
Stack Trace:
Devart.Data.MySql.MySqlConnection.i in ()
Devart.Data.MySql.MySqlConnection.Open in ()
in Quest.Toad.Db.Connection.OpenConnection (IDbConnection connection)
