It's not an error but a warning.

You don't set client charset, default it's iso8859-1.

Simply iso8859-1 can't represent all cp850 characters so FreeTDS complaints 
about. You can ignore warning and handle possible corrupted conversions or 
change client charset. You are using PHP so I think you output web pages. My 
suggestion in this case it's to use utf-8. This charset can represent any 
present and ancient language (even characters not possible on mssql) and it's 
supported by all browsers.
