解决用PHP连接狗日的SQLSERVER不能使用UTF8，导致乱码的问题

If you use freeTDS, you should change below lines on /etc/freetds/freetds.conf:

[global]# TDS protocol versiontds version = 4.2

To this:

[global]# TDS protocol versiontds version = 8.0;tds version = 4.2

and finally add this line:

# set charsetclient charset = UTF-8

这样就能用utf-8了
