我知道这个问题到处都是，我已经找了几个小时了，但我找不到任何有效的解决方案。相信我，我已经测试过很多了。
只要字符串中有冰岛字母，它就会给我:"
我在stackoverflow和互联网上尝试了所有的解决方案。但我就是不明白我做错了什么。
这是我的设置。
grabber.php中有以下代码:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<script type="text/javascript" src="//code.jquery.com/jquery-1.8.3.min.js"></script>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jqueryui/1/jquery-ui.min.js"></script>
</head>
<?php
ini_set("display_errors",1);
// attempt to remove strange characters
ini_set('default_charset', 'utf-8');
header('Content-Type: text/html; charset=UTF-8');
mb_internal_encoding('UTF-8');
mb_http_output('UTF-8');
mb_http_input('UTF-8');
mb_regex_encoding('UTF-8');
$opts = array('http'=>array('header' => "User-Agent:MyAgent/1.0'r'n"));
$context = stream_context_create($opts);
// SKRIFA HÉR VÖRUNÚMERIÐ
$ids = '824379-421';
$header = file_get_contents('https://domain.com/getproduct.do?id='.$ids,false,$context);
$json = $header;
$obj = json_decode($json);
$myndin = $obj->{'productImage'};
$voruheiti = $obj->{'productName'};
$verdmedvsk = $obj->{'normalPriceIncVat'};
$verdanvsk = $obj->{'normalPriceNoVat'};
$vorulysing = $obj->{'productDesc'};
echo $ids
?>
<body>
<div class="vorumynd"><img src="<?php echo $myndin ?>"></div>
<div class="voruheiti"><h3>Vöruheiti :</h3> <?php echo $voruheiti ?></div>
<br />
<div class="vorulysing"><h3>Vörulýsing :</h3><?php echo $vorulysing ?></div>

当我获取远程服务器报头时，我得到:
Array (
[0] => HTTP/1.1 200 OK
[1] => Server: nginx/1.8.0
[2] => Date: Thu, 06 Oct 2016 16:52:32 GMT
[3] => Content-Type: text/html;charset=ISO-8859-1
[4] => Content-Length: 4352
[5] => Connection: close
[6] => Set-Cookie: JSESSIONID=2A03A2B7A92D53CE7C166B4E9DA11DAC; Path=/resellers; Secure; HttpOnly ) Array (

[Server] => nginx/1.8.0
[Date] => Thu, 06 Oct 2016 16:52:32 GMT

[Set-Cookie] => JSESSIONID=C7DA983AC63F1117865CF98962336CAB; Path=/resellers; Secure; HttpOnly
)
在做json_decode之前，您应该将数据从ISO-8859-1转换为UTF-8:
$json = mb_convert($json, 'UTF-8', 'ISO-8559-1');
请注意，您需要在PHP中安装并启用扩展mbstring
我一看到问题就明白了。
有时候你只需要和别人谈谈或者把问题写下来
我把字符集搞错了
我使用的是utf-8，但我应该使用ISO-8859-1
因为远程服务器头响应了这个
希望这能帮助到一些人…
要打印出远程服务器头以查看要使用的字符集，使用以下代码:
$url = 'https://remote-domain.com/';
print_r(get_headers($url));
print_r(get_headers($url, 1));
