JSON、不正な形式のUTF-8文字をデコードできませんでした - 予期せぬPHP beahviour

JMS Serializer経由でREST要求の非直列化が終了しましたJSON、不正な形式のUTF-8文字をデコードできませんでした。この例外は、PHP関数json_las_errorがJSON_ERROR_UTF8という値を返すときに発生します。私は何時間も成功を収めずに、原因（よく形成されたUTF-8、BOMなど）を検索します。 UTF-8はよく定義されていました。この変更は成功で終了し、逆シリアル化した後JSON、不正な形式のUTF-8文字をデコードできませんでした - 予期せぬPHP beahviour

class JsonDeserializationVisitor extends GenericDeserializationVisitor 
{ 
    protected function decode($str) 
    { 
     $decoded = json_decode($str, true); 
     $error = json_last_error(); 

     switch ($error) { 
      case JSON_ERROR_NONE: 
       return $decoded; 

      case JSON_ERROR_DEPTH: 
       throw new RuntimeException('Could not decode JSON, maximum stack depth exceeded.'); 

      case JSON_ERROR_STATE_MISMATCH: 
       throw new RuntimeException('Could not decode JSON, underflow or the nodes mismatch.'); 

      case JSON_ERROR_CTRL_CHAR: 
       throw new RuntimeException('Could not decode JSON, unexpected control character found.'); 

      case JSON_ERROR_SYNTAX: 
       throw new RuntimeException('Could not decode JSON, syntax error - malformed JSON.'); 

      case JSON_ERROR_UTF8: 
       throw new RuntimeException('Could not decode JSON, malformed UTF-8 characters (incorrectly encoded?)'); 

      default: 
       throw new RuntimeException('Could not decode JSON.'); 
     } 
    } 
}

：folowsとして

class JsonDeserializationVisitor extends GenericDeserializationVisitor 
{ 
    protected function decode($str) 
    { 
     $decoded = json_decode($str, true); 

     switch (json_last_error()) { 
      case JSON_ERROR_NONE: 
       return $decoded; 

      case JSON_ERROR_DEPTH: 
       throw new RuntimeException('Could not decode JSON, maximum stack depth exceeded.'); 

      case JSON_ERROR_STATE_MISMATCH: 
       throw new RuntimeException('Could not decode JSON, underflow or the nodes mismatch.'); 

      case JSON_ERROR_CTRL_CHAR: 
       throw new RuntimeException('Could not decode JSON, unexpected control character found.'); 

      case JSON_ERROR_SYNTAX: 
       throw new RuntimeException('Could not decode JSON, syntax error - malformed JSON.'); 

      case JSON_ERROR_UTF8: 
       throw new RuntimeException('Could not decode JSON, malformed UTF-8 characters (incorrectly encoded?)'); 

      default: 
       throw new RuntimeException('Could not decode JSON.'); 
     } 
    } 
}

（json_last_errorは、switch文で直接ではありません）：それから私は、JMSシリアライザの変更コードを試してみました。この動作の説明はありますか？それはPHPのバグですか？ありがとう。

リクエスト自体を提供できますか？ –

同じデータをデコードしますか？ –

すみません。私はいくつかの重要な情報を指定していませんでした。 'クラスJsonDeserializationVisitorがGenericDeserializationVisitor { 保護機能デコード（$ strの） { $を拡張：私はあなたが見ることができるようにはい、常に同じデータをデコード*のみ生産で、私の地元的環境上の問題を再現することはできません* t = json_decode（$ str、true）; $ error = json_last_error（）; // SUCCESS $ decoded = json_decode（$ str、true）; //成功しました。スイッチ（json_last_error（））{// JSON_ERROR_UTF8 - それは私を混乱させるケースJSON_ERROR_NONE：ますreturn $デコードされ; ' – user2677847

あなたはそれを介してJSONを実行するとJSONLintは何と言っていますか？
