Yes, it's possible.  It's true:

    292         locale = setlocale(LC_ALL, NULL);
    293
    294 #if HAVE_LOCALE_CHARSET
    295         charset = locale_charset();
    296 #endif
    297 #if HAVE_NL_LANGINFO && defined(CODESET)
    298         if (!charset)
    299                 charset = nl_langinfo(CODESET);
    300 #endif
...
    400         /* if it's a servername */
    401
    402         if (servername) {
    403                 tds_set_user(login, username);
    404                 tds_set_app(login, "TSQL");
    405                 tds_set_library(login, "TDS-Library");
    406                 tds_set_server(login, servername);
==> 407                 tds_set_client_charset(login, charset);
    408                 tds_set_language(login, "us_english");
    409                 tds_set_passwd(login, password);
    410                 if (confile) {
    411                         tds_set_interfaces_file_loc(confile);
    412                 }

That's meant as a test of the host OS's locale support.  If you delete
line 407, tsql should respect the freetds.conf setting.  

The calls to locale_charset() and nl_langinfo() should be in libtds, to
establish a default client encoding if none is specified in
freetds.conf.  But they're not there yet, and TODO is a little out of
date on the subject....
