Description:
When I retrieve strings from VB (using ADO and MySQL ODBC 3.51 Driver DSN), characters > 127 are displayed incorrectly (spanish app).
I'm not shure if it's bug, but the guys at vbmysql.com told me to report it (http://www.vbmysql.com/forums/viewtopic.php?t=71)
Thanks anyway

How to repeat:
MySQL:
USE test;
CREATE TABLE spanishcontents (spanishstring VARCHAR(16));
INSERT INTO spanishcontents VALUES('Termómetro');  /* ascii(ó) = 162 */

VB:
Dim con as ADODB.Connection
Dim rec as ADODB.Recordset
Dim sql as String

Set con = New ADODB.Connection
con.ConnectionString = "DRIVER={MySQL ODBC 3.51 Driver};" _
                                    & "SERVER=192.168.10.43;" _
                                    & " DATABASE=test;" _
                                    & "UID=me;PWD=test; OPTION=3"
con.Open
sql = "SELECT * FROM spanishcontents;"
Set rec = con.execute(sql)
MsgBox rec.Fields(0).Value    'This shows "Term¢metro" instead of "Termómetro"

Note that I also tryed replacing the query in the VB code to
sql = "SELECT 'Termómetro';"

and the result was correct (The message box showed "Termómetro")

Sorry, but the bug system is not the appropriate forum for asking
support questions. Your problem is not the result of a bug.
For a list of more appropriate places to ask for help using MySQL
products, please visit http://www.mysql.com/support/

Thank you for your interest in MySQL.

What probably happens here is that the mysql command client and your VB GUI program uses different characters sets.

MySQL 4.0 doesn't do any character transforms like the one indicated in the bug report, so this is probably not a MySQL problem.

Except for escaped characters \ and things related to quoting MySQL will return in the SELECT exactly the same binary string the you inserted.

If this is not the case, please provide information that shows that MySQL does a character transformation.
