If mssql.charset = "UTF-8" can't get UTF-8 string , u can use putenv() to set FREETDSCONF dynamic.

Use this to check the runtime tds version...

mssql.charset "" PHP_INI_ALL
this setting is case sensitive, it can provide problms with connection to DB.
ini_set('mssql.charset', 'utf-8');
this setting this allowed me to connect.
ini_set('mssql.charset', 'UTF-8');
that one is ok.
regards!

Take care about mssql.max_procs = '-1'. It doesn't mean unlimited procs.
With the default driver, it's mean 25 procs.
See php.ini for more information.
If you're application is stress, mssql_connect may failed without adjustment.

There also exists a configuration option called 'mssql.charset'.
It will override the 'client charset' setting in freetds.conf.
AFAIK this will only take effect if the 'tds version' setting
in freetds.conf is >=7.0
