Question

有人知道这是什么以及如何解决它吗？ “OMG”

<p>After 32 years in its former location, this popular restaurant 
   and bar moved to the bottom of the Avalon Bay Luxury residential building 
   that's just a walk from Angel Stadium. Modern and welcoming, the expansive 
   space is where fans, locals and families gather for upscale twists on classic
   American dishes. Burgers here have a decidedly fun flair like “The OMG� 
   that is a burger surely meant for sharing (with many)--it's so huge that it's 
   served on a 14-inch bun. The restaurant also specializes in seafood with such 
   items as Chilean sea bass, mahi mahi and swordfish. The lounge also serves 
   signature drinks like  the Rally Monkey Martini in tribute to the mascot 
   of the Angels.</p>

这似乎是一个问题，因为在解码之前我必须在 JSON 数据上运行一个函数，否则 JSON 解码将失败:

function safeJSON_chars($data) {
$aux = str_split($data); 
foreach($aux as $a) { 
    $a1 = urlencode($a); 
    $aa = explode("%", $a1); 
    foreach($aa as $v) { 
        if($v!="") { 
            if(hexdec($v)>127) { 
            $data = str_replace($a,"&#".hexdec($v).";",$data); 
            } 
        } 
    } 
} 
return $data;}
