Instead of specifying tds version and client charset in freetds.conf, you may pass it as a parameter.
<?php $dsn = 'dblib:version=7.0;charset=UTF-8;host=domain.example.com;dbname=example;'; ?>

If you're using FreeTDS driver and you want to use "charset" parameter then you may have to edit freetds.conf (e.g. /etc/freetds/freetds.conf) and force connection using at least version 7.0 of the protocol.

tds version = 7.0

Charset parameter accepts all encodings supported by iconv (execute iconv --list to show all encodings).

when you connect to non standart 1433 port

for win32 use DSN like 'mssql:host=hostname,port;dbname=database'

for FreeTDS and DB-Lib use DSN like  'mssql:host=hostname:port;dbname=database'
