PHP mssql_connect正在截断特殊字符

Question

PHP mssql_connect正在截断短划线，短划线，重音字母和其他特殊字符以及之后出现的文本。

例如：

  

在MSSQL中：3 - 5年级   成为：3年级

也...

  

在MSSQL中：Sí和Sí   成为：S

代码详述如下。

ini_set('mssql.charset', 'UTF-8');
$link = mssql_connect($server, $user, $passwd);
$returnrows = mssql_query($query_string, $link);
while ($row = mssql_fetch_array($returnrows)) {
    variable = $row['row_name';
}

下面提供的query_string：

$query_string = 
"SELECT [Internal ID] as internalid
,[SKU] as sku
,[Title Name] as name
,CAST([Title Description] AS TEXT) as description
, ". "[SLP] as price
