I can't help you with the odbc driver, but if it works
correctly, everything should fit together after you
solved the underlying character set problem.

So let's try to debug with the old but trustworthy ISQL console.

Open a console window (you are on a NT+ system?)

Set the console's codepage to 1252 with:
chcp 1252

Start ISQL and set the connection char set to CP1252:
SQL> set names WIN1252;

Open your database, select the offending field:
SQL> select FLD from TBL where COND;

Now, I assume ISQL gives:
> Cannot transliterate character between character sets

Select using explicit cast (match your field length)
SQL> select cast (FLD as varchar(200) character set WIN1252);

Does that work and display the TM-Symbol?

O.K. "Dangerous Bend" sign ahead - do you have a backup?

Safe way: add a new column with character set WIN1252
and copy the data to the new column, using the cast
shown above

Hack: Change the metadata of the existing column, setting
character set ID to 53

After either of these surgeries, you should now be able
to get the TM-sign in ISQL without cast.

Now your ODBC access should work too, using WIN1252 as
connection character set.
