UTF8 字符编码之战 json_encode()

Quest

我希望获取带有重音字符的行.列(NAME)的编码是latin1_swedish_ci.

The Code

The following query returns Abord â Plouffe using phpMyAdmin:

SELECT C.NAME FROM CITY C
WHERE C.REGION_ID=10 AND C.NAME_LOWERCASE LIKE '%abor%'
ORDER BY C.NAME LIMIT 30

The following displays expected values (function is called db_fetch_all( $result )):

  while( $row = mysql_fetch_assoc( $result ) ) {
    foreach( $row as $value ) {
      echo $value . " ";
      $value = utf8_encode( $value );
      echo $value . " ";
    }

    $r[] = $row;
  }

The displayed values: 5482 5482 Abord â Plouffe Abord â Plouffe

然后使用json_encode对该数组进行编码:

$rows = db_fetch_all( $result );
echo json_encode( $rows );

Problem

Web浏览器接收下列值:

{"ID":"5482","NAME":null}

而不是:

{"ID":"5482","NAME":"Abord â Plouffe"}

(或编码的等效物.)

Question

The documentation states that json_encode() works on UTF-8. I can see the values being encoded from LATIN1 to UTF-8. After the call to json_encode(), however, the value becomes null.

How do I make json_encode() encode the UTF-8 values properly?

一种可能的解决方案是使用Zend Framework美元，但如果可以避免的话，我宁愿不使用.
