problem with _ character

Hello,

I am using ANSI odbc driver (11.0) on a W10  with a utf8 DB trying to :

SELECT * FROM table WHERE (name = ?);

with a name including a '_' character : '1170332_381-P364'

In the postgresql server logs, I see that it has been replaced with
'1170332[_]381-P364' and my query fails.

How should I do ?

Thanks.
